Air Door Actuator Replacement: 1994 Chevy Cheyenne C1500

1994 Chevy C1500 Air Door Actuator Replacement: I replaced the air door actuator in my 1994 Chevy Cheyenne C1500 and its a real fiddly job as the air door actuator is located under the dashboard on the passenger up near the firewall. If you are getting that clicking sound up under your dash in your Chevy truck like mine, then it's time to replace this part. I got my replacement air door actuator from LMC Truck. The part is called "Air Door Actuator - Air Inlet" specifically and the part# is 39-2601

Love how you even went out of your way to give extra detail cause no one does that anymore.. appreciate the video just fixed mine!

[@BuildYourOwn]

I appreciate that! It's all about the details

[@calebsampson3698]

I'm about to fix mine now!

[@lildudechevman]

If you cut the slot where the screw goes on the very end, you can start the screw first then slide the actuator into place, then tighten the screws afterwards.

[@JesusSaves86AB]

Good tip. Thanks

[@lylejohnston4125]

I was thinking of trying that. Will it let the actuator swing into place on the shaft? UPDATE: You were right after fighting that little bastard all the way out, I screwed it back in about 2/3 and cut a slot in the actuator. A little tricky getting it to line up ( I already had the blower motor removed so, it was easy to lift the door to align the shaft) But, well worth it. Thanks Armando! PS, it also helps if you cuss at it a lot.

[@Iloveyhwh_1974]

Good to know. Ty!

[@rockrollresale2668]

Maybe start the top bolt first, with the part loose and lifted hand access may be easier. Then lower on pivot into place and seat it.

[@SimonTekConley]

The trick is, take the entire dash out of the truck, then replace the screw.

[@jamesandrews8667]

I used a 4 1/2” angle grinder to cut an approximately 1 1/2” wide x 3” high opening in the firewall in the engine compartment after taking a bunch of measurements as to where I needed the hole. I didn’t cut the side closest to the center of the vehicle just used it like a hinge. Then bent the little panel open and removed the screw. To close it up I hammered the flap shut and neatly applied a two pieces of silver aluminum tape. Works good, looks ok. This is a 30 year old work truck so no one will be taking pictures of my art work at a car show…

[@fauxque5057]

That's how I replaced my AC evaporator. Cut a hole in the firewall and pulled it out from the engine compartment. There is one small screw inside the case that has to be removed. Took a while to figure that out.

[@utahyork3338]

After all that work, it would drive me crazy not to have that last screw installed! Come on Frank! Be a hero and get it done. I saw a video and the guy taped the screw to a socket and got it started with his fingers. Then used that 1/4 inch ratchet with the flexible end. Great video and information.

[@humbertoadame8055]

Put the screw through the hole . Slip a small o-ring on the backside holding it in place .Put your actuator in place then tighten the screw. This trick works on various applications. I keep all sizes of o-rings in my toolbox for this very reason . Hope this helps .

Thank you for this video. I’ve put this off for about 3 years now because I can’t figure it out and I am scared of getting it out and not being able to put the new one in.

[@erickruse4679]

yup, I'm huge with huge hands and I've been listening to that thing for years now. Since the AC is original equipment and doesn't work, I'm now thinking about just snipping those wires from the top. done.. :)

Thanks for this, I watched your video and did mine. Instead of the top screw, I shoved a zip tie through the hole and wrapped the other end of it up in the frame around the relays just so it serves as an anchor point.

[@kevinblackburn8735]

Pro tip: use a long flat blade screw driver and pry against back of 1/4” ratchet. It keeps enough pressure to back out screw the whole way and keep socket spinning as it gets loose.

[@lonniebrock3282]

Use longer screw with washers where screw sticks out enough to get socket on it

Thank you again

[@warrenfranz7980]

another thing to help keep the screw there is that black windshield putty.. good sticky stuff and hold well if you just place a dap in the socket then add the screw in. Great job on the vid! thanks!

Wow that's a tough repair! On my 99 Tahoe I just made sure that the blend door was closed and removed the power plug from the actuator so I'm always on recirculate which is just fine since I live in Florida and never turned the recirculate off to let the outside air in.

[@BuildYourOwn]

Much appreciated!

[@BuildYourOwn]

I purchased the part from LMC Truck online. Here's the part number they use, but it's easy enough to search their site by year make and model. (39-2601 AIR DOOR ACTUATOR-AIR INLET)

[@irishuwould5185]

I really like your detailed videos man. I put a whole new ac system in my 94 when I bought it and it blows semi cool air and weak air flow. Also when setting is on the face it still blows from the defrost and fogs up the windshield on the outside. I removed the blower motor and cleaned that out and cleaned the evaporator which was a job in itself especially in Texas heat. Well it did help with the air flow a bit and it seems a lot colder but it still blows from the defroster and fogs up the windshield. I know the 95 and up has the air flow distributor which you have to drop the dash and steering column and I heard it’s a pita to do. I’m not sure if the 94 and under have those. If not maybe it’s the actuator on the driver side floor board. I’m going to spray it with WD-40 and see if it helps, maybe it’s age it’s just not opening all the way. I hope that’s the case.

First off great vid! Leaps and bounds better than what was out there omg the subject! I do have a question however not directly related to the actuators. Do you know where the ducting is that allows air into the cabin? I have a hot air leak in the summer and a cold air leak in the winter. I've heard that a foam seal (I believe in the plastic heater duct) seals to the cowl? Can you or anyone else confirm or disconfirm this?

[@freddietellez8737]

You probably all ready got it but it take less then 5min. You need a 8-12in 1/4in with a 9/32 socket 🔧 and 8in long needle nose. So reach up and set the screw push it tight in the hole with your finger tips while your siting out side your door use your left hand to hold the wrench u will feel it sit on the nut test the your set while moveing the wrench side to side up and down to no your seated then slightly pushing it in then with your right hand and finger tips slide it up tords the back and grab the socket the u use your right hand to squeeze while slightly pushing it in then at the same time start with your fingers start wratcheting the wrench it may take a few times to get it started but after that it will go right in just snug it down and your done pretty easy. If u need any more info soot me a message. Hope this helps

[@twoutdoors515]

Hi I have a 93 c1500 my climate control flashing arrows do I think it’s the actuator I’m not getting heat

[@1Splat]

I need to do this for my truck. I wonder if you can swap the original metal socket-like piece with the new actuator's plastic one? As for the back screw, I've also used a tiny drop of crazy glue on the screw head to keep it from falling off. Just a tiny amount is all you need. Thanks for the video!

[@dk_wave9300]

We have our dash out bc we are replacing it and it was still a pain to get to. We got it out w a very small wrench- me turning from the top and my husband pushing on it from underneath. To get that top screw back in we had to move the computer out of the way. I used my nails to get it in place and turn it just enough to get it started. And then again he held pressure on the wrench from underneath while I turned from the top. I was the one saying just cut the wire the whole time though. Took us about 2 hours from start to finish with a lot of breaks for frustration.

[@marqueswilsonn]

Just pull the whole dash so you can replace all three actuators and the blender doors and heater core and evap core. Worth it. Cuss once cry once

[@tubehound69]

Mine began clicking about 15 years ago. I just unplugged it. I've put off changing it because it looked like it would be a hassle getting to that one screw. In the summer time I'll plug it back up, get the recirc door open so I can have max AC, and then unplug it again. In the winter time I'll have to plug it back up to close the recirc door otherwise it just recirculates the humidity in the cab which kills the effectiveness of the defroster. Maybe I'll go ahead and finally tackle the job, but I'm not looking forward to it. Maybe my bore scope will help get a good look in that tight place. Those things are as handy as a two pocket shirt.

[@kaosofthe4horsemen-Redhorse]

The screw you are having trouble with Get about a 1 foot long piece of a vacuum line big enough that the screw head will fit in it tightly and start the screw. The vacuum line is flexible enough. Try it it will work an old mechanic trick.

I have a 99, I tried everything to put this job off, We travel through Amarillo often and the dairy farm outside of town is just about enough to make you want to throw up especially with all the rain. Well, Long story short, someone already replaced the actuator and it went out again. Do you remember how many tabs were on the door that the actuator went over? I think there's supposed to be 2 but I can only feel 1 on mine and someone broke the other one it's not closing.

[@rustypipes6339]

I have been listening to my air door actuator for at least 10 years. I had no idea what the source of the noise was, figured it was some sort of vacuum-operated doohickey. It is good, sort of, to know the cause. I have a question: My heater core leaks, has for at least 12-13 years so I bypassed it. I live in Texas and there are probably less than 20 days a year that I actually need a heater so it hasn't been a big deal. If I remove all of the stuff I need to remove to replace the heater core, would that make replacing the actuator easier? Thanks for the vid. It is going to be a big help when I finally decide to fix my problem. Patience will be my biggest challenge. Thanks again.

[@BuildYourOwn]

I think I lasted two weeks (if that) listening to that clicking sound. I think if you're going to remove and replace the heater core, not only will you have better access, but you should be able to get at all the screws much easier. I wrote a good little article on the air door actuator locations on my website. Most importantly there's a great diagram of all three air door locations and even the heater core can be seen. You should check that out. Thanks for watching. www.buildpriceoption.com/air-door-actuator-locations-1988-94-chevy-and-gmc-truck/

Why is it always that actuator that fails? When I did mine I couldn't get to the tough screw. It needs two screws or it gets jacked up when it tries to operate. I'm not proud of how I made it work but after 5 years it still works. I stuffed a tennis ball up in there and it holds the actuator in place fine. A couple of years later I found a tool that would work perfect in that spot. It's called a Tite Reach. They have them in 1/4" and 3/8ths. I bought the 1/4" version with the intention of replacing thst screw but the tennis ball is doing just fine. I have used the Tite Reach several times with several projects.

[@djjenkins599]

I’m thinking about going to take a look at truck to purchase by owner. It’s a 91 Chevy. They did tell me the ac actuator shuts off or pops something to that nature when they turn off the truck. I had them send me a video of the truck running and it does make a clicking sound as they turn the truck off or right after. Is the ac actuator that’s causing it to make that clicking sound when the truck shuts off does that affect any other features of the truck? I’m not sure how many are on it or where or anything but I want to try to fix it myself at all possible.?

[@c2jacks]

My 02c when you are ready to insert the actuator, put all 3 screws in the actuator. Easiest way to explain how to retain them in the actuator is to explain where I got my idea. Look at an electrical wall plug. There are two screws attached to the plug that have a thin piece of plastic on them. They secure the plug to the plug box. I took 3 of those off some old plugs and put the screws through the actuator and secured them with these thin pieces of plastic. When you put the actuator in, and you have all 3 screws lined up. The two the author of this article got to are done first. The hard to reach one has to be literally pinched as hard as possible with the plastic because you do not want to "ratchet back" and have the screw go with the ratchet. So make sure the third screw is really jammed with the plastic. I broke 3 pieces of plastic from electrical plugs before I was able to get one that would hold the screw on the 2-3 clicks you get out of the ratchet. Then, hold your breath and tighten.

Then, just tighten it up? Or is even that to hard to reach? I figure if you can get a tool on to loosen then you can get one on to tighten. Is it just handling the screw that is the problem?

[@katoomer4524]

Try a drop of hot glue to hold the screw in place while you position the actuator, it will break loose when you put a wrench on it. Also if you can use a 1/4” air ratchet with a deep socket then it should be a piece of cake. Air ratchet 20.00 harbor freight.

I've not been to keen on replacing this, as I've heard it's a big pain and haven't found any videos to confirm/refute that claim.

I'm not sure why your defroster isn't working. I think you put in a different actuator than me. I think this because the one I replaced controls the fresh and recirculating air. There are three air door actuators on these trucks. Sounds like you may have replaced one of the others. I just created this page on my website showing a diagram of the air door actuator locations and explaining what each one does. Check it out. Hope it helps. www.buildpriceoption.com/air-door-actuator-locations-1988-94-chevy-and-gmc-truck/

Iam not getting power to my ac where it shows green when u control the climax will it be a relay that in bottom off glove box

Perfect how to video! No way no how getting to it from top, at least on my 93 Silverado.. I was thinking no need to put the top bolt back in if I can get it out about the time you decided not to so yay! I was able to pull the actuator out the bottom and take wires off fyi.

Right on and glad it helped! Thank you for watching.

I love this truck

Is this actuator the same thing as the blend door actuator?

[@mdkzztop]

Would that be causing issues with my defrost not working? I have a 94 1500

I used the tire iron that is under the back seat and pried it out after removing The front bolt. It was then easy to remove the upper bolt.

The issue mine is having is. The climate control area on the dash, where you control the "triangles" that indicate temp and the "blend" from the vents coming from the dash, to the feet... Will repeatedly blink, and it's stuck on defrost.... Do you think it's the same actuator as the one you did on this video, or one of the other two?

Yours is the easy one by your feet on the driver's side.

[@davidlaning3613]

​@@davidkelley5839 Sorry for the late response, but I found a replacement at my local pick n pull, swapped it out quite easily as you mentioned it would be! I appreciate you passing off that tid bit of knowledge sir! It's helped me the past couple of winters

Well sonofabirch. Just did my blower motor and heater core, thought the clicking was the blower motor. Time to pull the dash apart again.

The damper is for fresh air??
