Both this and your other "how to repair" video were extremely helpful. Thank you for sharing with the IS300 community. I'm going to attempt the replacement today, and will hopefully have some heat blowing back into the car again very soon. Update: Well, the replacement servo motor did the trick, we now have heat again, and the grinding noise is gone. The job should have taken about 20-30 minutes, but that darn hidden screw in the back was really a pain to get to and remove, I must have fought with that for nearly an hour. Finally helped to slide the tube padding/insulation up and out of the way to get a little more room for the screwdriver. That 3rd screw was very frustrating and really tried my patience. For some reason putting it back in during the reinstall wasn't nearly as bad though. Thanks again - very helpful!!

[@1947froggy]

Glad to help, getting cold. :)

[@Blaze49AzSd]

Thanks Froggy, great vid. I’m working on a Lexus IS 250 2014. It’s more compact near the actuators then your vehicle. The only way to remove the actuators is by dropping the whole housing for the fan motor, To make room. I need to figure that out , the bolts are not all visible. I’m doing a little at a time , so frustrating . You are motivating me to keep going.

[@antoniobrown5002]

Thank you sir I really appreciate this video you have helped me out. AC is blowing cold one day and then it stopped. I figured out it was this part right here in your video and now it blows cold

[@emmanueldelacruz4366]

Thanks Froggy, I've fixed my Lexus so many times thanks to you man!!! you're awesome!!

[@sergedenovo2389]

Yup

[@sergedenovo2389]

Froggy, is that arm supposed to move? At what point? Do you remember?(mine doesn’t no mater what I switches I hit on the control panel. Thanks man.

[@lebronjordan802]

Thanks for sharing I just changed my servo motor today and saves me hundreds of $$$... the shop where I took my car was going to charge me $885.00 for parts and labor! I said no thanks and ordered the part from ebay for $70.57 and replaced the motor myself after watching your video... thank you so much 😊 Froggy!

[@1947froggy]

Love it, that's why I do these. Dealer ripoffs on folks who can't afford it. Or just don't want to pay so much for a little fix. :)

[@lebronjordan802]

froggy keep your video coming you're helping a lot of people! You rock 👊!

[@lebronjordan802]

froggy just subscribed to your channel 😁!

[@xtiann442]

Thank you very much for this Froggy, I have been following for a long time and am now going to finally buy the part and do the install. You're an asset to the community!

[@1947froggy]

Should be fine, go slow, refer back to the video as needed. :) Post how it goes.

[@fscott7840]

When you start the car you will hear a clicking noise. This IS300 is my daily driver for the last 21 or 22 years. If you turn the temp to extremes hot/cold a few times, it will stop most of the time. The air for now at least will move correctly thru the vents. This has been going on for years. In the winter when the car is bone cold or when the temp is hot, it will make the clicking noise. Once car is warmed up and driving for 10 minutes it seems to behave and I forget about it. However, I don't want to wake up and find I have no heat in the winter and cold in the summer. I ordered the part and will let you know the results once installed. Thanks for the detailed description.

[@1947froggy]

Thanks, post back how it goes.

[@fscott7840]

Purchased the part. Then it stopped making the clicking noise. Still waiting till I have to install.

[@essietel1196]

Thanks Froggy. This helped me out in finding what to look for. I have a right hand drive (Australia) 100 series Sahara, which means that rather than being able to remove the glove box, its on the driver side. Getting access to the bolts on the right hand drive is an absolute nightmare. I even had an endoscope to use and see the screws that need to be removed. I just can't get my hands in there without disassembling the entire centre console and removing all of the AC ducting that was in the way.

[@1947froggy]

Yes, I relate, buried parts that fail are the worst. Hours of labor for a $10 part. Ugh.

[@gmen0521]

mine was the easy one thats first before the one he was talking about. my 01 is300 would blow cold air even in heater mode. so i bought an aftermarket unit for around $55 and took me 1 hr to do first time ever doin it. just be careful with vents n there clips. and the small screw driver does help for the rear 2 bolts

[@gmen0521]

great video by tge way brotha very helpful

[@WeekendHobbyMechanic]

My 2007 Camry blows cold air on my passenger side only. Driver's side isn't cold at all. Which servo could be the culprit? Thx .

[@Yuksan]

Hi, My is300 isn't blowing heat, only cold air. I just changed the thermostat and that wasn't the issue though it was in bad shape. The air mix servo does make a noise on start up for about 9-10s then stops but the door seems to move fine between the last two settings.

[@1947froggy]

If you hear hot/cold servo move and it sounds correct, you MAY have a clogged up heater core. I hope not it's a bitch to replace. See if you can shove your hand up near the core with hot selected & see if it's hot/warm. :)

[@Yuksan]

If those two pipes near the motor run to the core, then those are hot.

[@sergedenovo2389]

Thanks for the video. …you still have the car?

[@1947froggy]

no

[@mysteryman_ph]

On my way to DMV early this morning, I noticed that after been driving for more than 20 mins my car still blowing cold air. I think I have a same issue, I let you know once I fix my car but I’m almost pretty sure that my actuator went bad as initially I heard squeaking noise on my initial startup and I don’t hear the click when I move the thermostat selector from 65 to 85.

[@1947froggy]

Probably that's it. Post how it goes. :)

[@owe140]

Thx for your video. Subscribed. What are the symptoms that let me know that this part needs to be replaced? Thanks

[@1947froggy]

The control does not change where the air is supposed to be directed.

[@x3xFLiPSiD3X3x]

So this isn’t going to change wether you have hot or cold air? I just bought the part and going to install tomorrow hoping to get some heat for my girls car

[@donathanpaula86]

My ac blows hot on the right and cold on the left side. Which servo motor do I have to replace?

[@1947froggy]

I would get a schematic of the hvac and look for one called a diverter. I don't have that vehicle now.

[@Sulto_]

Is it the same process on is250 2015? Garages asking to remove the full dashboard to change them!

[@1947froggy]

I don't know , that is a different year.

[@ericli806]

So I am not getting hot air in my vent? is this my problem? its also making weird noise when i start the car and it goes away after like 10 sec

[@1947froggy]

Well if you get cold air (AC) good but not hot air, then the servo & mix door are doing what they should. Is that the case?

[@garydelr5757]

I cant find an aftermarket version of this part. Did you have same problem? Thanks for this vid.

[@1947froggy]

Just buy original, better quality.

[@marcusferro6134]

hey froggy im having a similar problem with my 04 is300. The ac will sometimes turn on when the dial is in the off position. The ac light will also get stuck on either or off. This is a reoccuring problem and sometimes it will fix itself for a few months. just seeing if this is the issue you had. Thanks

[@1947froggy]

Try to figure out if the actual a/c compressor is running when the light is on, or off when the light is off. This does not mean the pully spins as it spins all the time. Could be the circuit board is shot. Just a guess.

[@JohnnyBoy88-]

Would either one of these servos that you replaced/worked on cause the driver side to get cold/ac air and the passenger side get warm/hot air?

[@1947froggy]

Cause? You mean would the proper installation of the servo "cause" the system to work incorrectly? No these servos "fix" the incorrect function of the system. Thanks.

[@Guyhakverdi]

Thanks for sharing froggy! Why there are 2 of them next to each other? What does the other one do? If the one change control the temperature.

[@1947froggy]

hot/cold, dash/floor, recirc/outside air.

[@mikejamieson4252]

So this is for the temp one correct? (Not mode)

[@1947froggy]

Mixing hot and cold air to get to desired temp. :)

[@richierodgers3303]

Nice job boys watched whole thing.

[@1947froggy]

Thanks! :)

[@xavigsr]

Hello my front vents don't blow any air cold nor hot but my 2 sides bottom n top of dash do work perfect. Any idea what mite be causing it?

[@1947froggy]

Probably mode sensor(s) watch a few is300 videos, not just mine. :)

[@mrdude3540]

How did you take off the old one. I have pipes running right in front of the bolta

[@1947froggy]

Look at my other videos, thanks, google froggy lexus is300

[@mrdude3540]

@@1947froggy thanks dude

[@interceptfist]

hi, is this the part to replace if turning the heat to max stops the clicking noise? if i simply increase the temperature from 60 or 70 to MAX, the noise will stop. so, will replacing with this exact part fix my problem? or do i need to replace the other servos as well?

[@interceptfist]

also, currently my hot and cold temperatures work perfectly. i just keep hearing the noise if temp is not at max hot.

[@1947froggy]

Probably yes, however, it could be the plastic track that I show or the door itself. No guarantee it will fix your issue.

[@stanleesian7264]

Hey man. AC light on knob is blinking and AC stopped working. Should I jumped into this actuator or should I looked for other possible problem first?

[@1947froggy]

No, the actuator replace will not fix dead A/C. :)

[@khalidmohammed6428]

Have you tried this on a gs300? The heat pipes blocks the bottom screws

[@1947froggy]

Sorry, don't have gs300. :)

[@DGC904]

Is this the same part for gs300 02

[@1947froggy]

I have no way to know that, sorry.

[@logankraaima9349]

Mine won’t change from top & bottom to defrost. It’s always on top & bottom. Which actuator will I need to replace?!

[@1947froggy]

Not the one I did, the one I did is hot/cold. I'm not sure on which other. Take it partially apart & stick your head under & twist the knobs. You will see the servos moving (or not). That should narrow it down to the one you need. :)

[@vpcreations7805]

Hey foggy ... thank u for ur videos... When I turn my AC .. my center vent is not blowing air but my 2 side one does blow cold air .. I’m not sure what’s goin on? Thank you

[@1947froggy]

Review the videos on actuator door servos. :)

[@3guavamidnit]

Hi Foggy...I have a question...I have the exact same car...but my climate control unit is not working....the 3rd knob to the right where it say A/C. Although the arrow was on an OFF position but it still blowing air very loud. I don't know if it the control unit is not working or the blower motor resistor is not working? Can you help me?

[@1947froggy]

I have not done that myself, Off with air blowing seems to indicate a controller sw/module somewhere. Please post back when you get it. Maybe try alldata for schematic.

[@3guavamidnit]

@@1947froggy ...actually the control blower motor is not working. I just replace a new unit now it working fine...

[@ShaunKore]

Ok so I am going to run my scenario by you and maybe you can assist? I have a 2002 is300 and when i am NOT using Auto mode temps and directional flow seems ok... when I use AUTO for both fan speed and Directional flow i don't get nearly as hot air as i do in Manual mode? Auto mode at the most gets slightly warm at MAX TEMP? But in manual mode it gets very HOT! Any Ideas?

[@1947froggy]

That is interesting, if you get max heat in manual mode then it's NOT the actuator. I am GUESSING the control (circuit board) or more likely the temp SENSOR is having trouble. I have not accessed either myself. :)

[@91celsior]

What would cause a heater to kick on by itself

[@TheSquintz21]

@froggy I appreciate the video , my current situation is my ac is blowing hot and only through the dash no matter what setting I have it on . Could it be this servo? I hope so seems like an easy fix

[@1947froggy]

If it's blowing only hot it is more than just a servo, fixing the servo will not make it cold. Fix the a/c and the servo. Thanks.

[@TheSquintz21]

froggy thanks I’ll fix servo first

[@TheSquintz21]

froggy isn’t there a servo that deals with the climate knob, ? Sorry I don’t know how to explain it

[@markmanning2246]

How long does the work take to replace this part? I took it to a shop and they wanted to charge for 5 hours of labor.

[@1947froggy]

That seems high, but it's not as quick as an air filter. There is a "book rate" they use which is an estimated average time for average mechanic to do it. Good mechanics beat it by as much as 50% less. Ask to see the book rate. :)

[@markmanning2246]

Thanks. I have watched this video a couple of times and debating trying to do it myself. Would you mind listing the tools and sizes that you used.

[@markmanning2246]

I will check another auto shop for their price and the book rate. It is getting cold where I am located and having the air not turn into heat is a problem

[@1947froggy]

I don't recall any special tools, but I don't have time to do that, sorry, really busy. Really short screw drivers & CORRECT sizes helps.

[@chrispants8267]

@1947froggy what is that tool and how did you make it or get it? Thanks 8:14

[@1947froggy]

Hex hand driver (Amazon) like a screwdriver handle for hex bits.

[@chrispants8267]

Thanks. What is that blue knurled part though?

[@Bellgrande]

Is there a link to the direct part, I can’t seem to find it anywhere

[@1947froggy]

Try rock auto drill down or go to local dealer.

[@Bellgrande]

froggy oh thx! I just bought it last night for 155 off of eBay

[@StarTrac100]

Froggy U have some great Vids..... I have a question mine is stuck on the vent facing your face I cant change it to the floor or defrost do you know what that could be and mine is build into the Nav

[@1947froggy]

99% it's the mode servo. Doing any of the servos is mostly the same just different stuff to remove to get at it.

[@rexvisitor44]

Is this the part to replace if with AC on driver side blows cold but passenger side usually blows hot. I also hear a grinding noise. Thanks in advance to anyone who can help. Car is 2000 GS400 with 150k.

[@1947froggy]

Grind is gears not meshed.

[@charleswhite206]

where does the power come from to the control blower motor on 2001 Lexus 300 gs replaced motor still want work

[@1947froggy]

It should be fused, get detail of fuse panels, I don't have sorry.

[@hd221813]

Please, could someone tell me the exact Toyota/Lexus part number of those 3 screws that keep in the correct place the actuator motor?

[@1947froggy]

Suggest reuse originals, if you lost one take the other to a hardware store & match, if you must order from a p/n sorry don't think that's an option unless someone else has it. :)

[@559rick1]

My is300 makes noise but everything works good what servo is it?

[@instasingingvids3529]

Ricardo D It may be the upper one the one that controls the blowing mode. Blowing straight at you on the floor or to the windshield may need some grease

[@nxvn350]

Hi, my heat barely blows on the passenger side alone. Do you think it could be an issue with the heater core?, I do have a replacement one but I haven't gotten around to replacing it yet.

[@1947froggy]

If you have heat "elsewhere" then your heater core is ok. Probably the mode door. Do you have DUAL control, driver side vs pass side? :)

[@nxvn350]

froggy Thanks for the quick reply! When I switch on the heat, the driver side just feels as if it's blowing normal cool air, and the passenger side barely blows a bit of warm (not hot) air. However, the AC does blow ice cold on both sides.

[@nxvn350]

froggy It also sometimes smells like burnt coolant..

[@1947froggy]

That is usually a heater core leak, ever see any wetness inside the pass footwell?

[@nxvn350]

froggy I'm not too sure, I havent ran the heat in a while. I'll have to check that out and get back to you! thanks.

[@DennyLor94]

So I have the servo problem and my heater is not working. Are those two related?

[@1947froggy]

Yes. :)

[@1947froggy]

Yes.

[@charleswhite206]

fan motor good
