This is what I call a well seasoned mechanic!

[@RJ-lk5pj]

Hands down.. one of the most competent well rounded & honest mechanics on youtube. You don’t have much face time.. a lot of the diagnosis & brain storming- direct example of what he thinks could be and in the near future or may Become a issue.. A no no nonsense approach to the technical side of automotive care- Jim.. I watched and learned from prior videos to replace brakes and it’s your teaching methods work for me; hands down better then any other channel. Keep up the good work.👍🏻

[@35milesperhour94]

You must've done this before Jim. I was amazed at how you were able to find the leak locations without using fluorescent dye.

[@TheDisgruntledMechanic]

a good time of the year to show this video! nice work Jim! hope all is well.

[@steveg5576]

That's a thorough job...right down to checking the temp. My work truck compressor was short cycling. Needs a can or two most years. Been using those short hoses for charge. Finally got some gauges last year to do an addl charge. Just checked the temp yesterday. In a few minutes of driving the AC comes out 41-42 deg. Hard to believe...that's cold. I've been settling for 50-52 deg in previous years. Thanks Jim and KZbin.

[@txsviking]

Another great video! Love the way you explain things as you go along. Have a good 4th.

[@MrBwalendy]

You worked very hard to provide as much information as you possibly could. That makes for an informative vodeo and makes you a great person. Thanks for being you.

[@jimthecarguy]

I'm happy to help. Watch for the next free tool giveaway coming soon.

[@neilfigueredo7041]

Great video ... For a gury like me it's really helpful to see what the heck happens to a/c system Nice job... Thanks

[@adearmas2003]

[@stevenmalone1577]

Very underrated mechanic

[@theunexpectedmechanic4684]

Great job , Jim. Learned a lot.

[@samrugtiv5563]

very well done Jim thanks sam.

[@ahraitch6218]

Brilliant. Great video! Thank you!

[@BobWhite777]

When you check the pressures should the engine be at idle or at higher rpms?

[@apollocreed3549]

good video Jim

[@carlosysoniasanchez6429]

Hi Jim, I have a 2007 Avalon tha air has a bad smell with ac on or off. Any tips on how to get rid of the smell. Thanks

[@toroon]

Yeah, the accumulator in my Saturn is rusted out too. After checking prices my wife said "Buy a new car or roll down the damn window" I hate it when she's right.

[@wayneo1269]

lol

[@toddt6730]

what about if it only rums cold in fast traffic,but blows warm at traffuc lights ir slow traffic,the freon is fine,dont know what to check next,this is on a 2006 saturn ion

[@petertyrrell6690]

Very helpful. You are a craftsman>

[@jimthecarguy]

thank you

[@barryp5334]

I had nowhere else to ask this, and can not find anyone that has helped. I have a 1999 Buick Park Avenue. My A/C stopped blowin out of vents. Floor and defrost only. I pulled the head, table top teched the inside. -5 re-spot solders were needed, as some seperate from the board from age. Thought that may have helped. No go. Correct me if I'm wrong but from what i checked there are a couple door actuator's that are in the dash. I have seen the one by left of glovebox is one that people said replace that one. Just want to be sure. Are they all the same when I order one. Do or would you know which one I may need to replace? Also "2" under left side of dash? I'd sure appreciate it. Love your vids, you've been great help in other issues!

[@abubakarharuna9523]

Hi Jim, You are a good mentor. please my A/c Witch developed a fault and my technician bye pass the circut and run a cable to the compressor. can that affect my a/c thermostat? Thank you

[@jimthecarguy]

abubakar haruna it is possible

[@neutrodyne]

I have a question I am hoping you can help me with. I have a 2008 Buick Lacrosse. On a hot day when I turn on the AC the inside blower will come on high and the compressor clutch engages the compressor and the compressor turns fine. Both of the condenser fans also turn on but no cold air. Here is the strange thing. With the gauges both connected there is no difference between the high side and low side pressures even though the compressor is turning. When the AC decides to start cooling the pressure all of the sudden change as they should (the pressures then look reasonable) and the AC will work fine for the rest of the day. This is an interment problem. I have 2 guesses on this one the expansion valve is stuck all the way open or for some reason the compressor has a problem. What are your thought on this? Have you ever ran into this type of problem? Thank you in advance.

[@JesusSanchez-ee7re]

Has new a/ c Freon and new condenser fan please help

[@simondaka2217]

This ac mechanic is prety demn good.

[@haywardsautomotive6156]

Nice job Jim. All I've been doing lately is AC work...people need to be cooled down here in HOTLANTA!

[@jimthecarguy]

Thats great.Up here most of the time people hear how much it is a drive without the ac

[@haywardsautomotive6156]

They'd melt down here at @100 degrees and @+90% humidity

[@harrisonserrato900]

Excelente video super helpful. Buddy my AC compressor click on and off repeatedly every 5 second. I wonder what could be wrong? Thanks very much

[@jimthecarguy]

It sounds like it is short on freon .Did you check the pressure?

[@lionschannel.3822]

Good video. Anyone out there who knows the name of that plastic tool used to squeeze the spring to rid off the pipes from the accumulator to tell me please. Is it available in Amazon? I always find problems trying to pull out such kind of pipes from Ford Transit evaporator.

[@dotcom2936]

how can i install petrol and gas switch change.

[@joshuaorton7540]

Question! Recently, the mechanic replaced the compressor in my Chevy Impala and charged it and the AC started working fine. It worked great for like a week and the compressor started making grinding noises especially when the car is on idle and upon inspection, it was discovered that the compressor was going bad and the AC stopped working again. Do you think there is something we are missing here or just replacing the compressor again would be fine?

[@jimthecarguy]

I do a live stream on Sunday night 7:00 PM (EST) .I will talk about this problem.I hope you can stop by

[@fieldsofomagh]

Another cool customer.

[@jimthecarguy]

Hahaha.I like that

[@29auto30]

Do you have a part # for that line removal tool,the one I use is junk,looking to upgrade. thanks.

[@jimthecarguy]

Sorry I bought them a long time ago.Heck I don't even remember where I got them.Lol

[@OneAuto]

Nice job Jim.. Stay cool man :)

[@jimthecarguy]

The best part of that job was the road test to make sure the ac worked .Lol

[@OneAuto]

Haha yes definitely the best part!

[@Ottonic6]

I believe, if you have an orifice tube, you will have an accumulator. If you have a receiver/drier, you will have an expansion valve... Also an accumulator is on the low side, A receiver/drier is on the high side.... so, expansion valve or orifice tube... Receiver/drier or accumulator.... Don't quote me, this is just my belief.

[@broken1965]

Jim nobody uses fender covers anymore? nice diagnose and repair

[@jimthecarguy]

I do sometimes but not to often.Thank you for stopping by.

[@sirsweetness8332]

Following up on my AC project today...I am at the mercy of the postal service. I ordered green AC O-rings but they did not arrive as the shipping stated. I did put in the condenser and compressor. I left the seal on the condenser and I had to change over some electrical and brackets from the old compressor. when I took the inlet out of the old condenser, a lot of metal flakes came out. I took the lines off and flushed and blew them out. now waiting on O-rings. NOT going to reuse old ones. Bummed...I wanted to finish this today.

[@jimthecarguy]

Yes the USPS .Hurry up and wait.Lol

[@sirsweetness8332]

jimthecarguy Getting plenty of experience taking these on and off. bottom of new compressor will not seal. would only pull 9 inches of mercury. my son and I heard the hiss of air being sucked in from the bottom of compressor. Sending it back!!!! I ought to charge them for labor

[@yaseenhashim8538]

thanks too

[@jimthecarguy]

Thanks for watching

[@johnkimmel2612]

Even though gauges showed no pressure initially, I have learned to pull it down anyway before removing any line/hose near my face. Lol that refrigerant tastes nasty.

[@federiconovales9111]

I'll see your video a wonderfull job for me coz I'm only new this kind of job Mr. Jim. can ask some questions I'll have Elantra from hundai model 2017 the problem is the compressor is not work, I'll bring it to a/c car mechanic he told me change the compressor but is new one year and two months only I'm here in Riyadh Saudi Arabia you sir very high price this compressor here when the a/c mechanic he check the pressure it's have il think the coil coz not compressor is not working have a nice day pls give me some advice Mr. Jim

[@ISS4935]

Federico Novales take it to Hyundai, should be under warranty

[@federiconovales9111]

thank you sir have a nice day

[@ISS4935]

also I should mention, on newer Hyundai`s you can not look at the compressor and tell if it is turning on, there is no clutch, rather it has a swash plate, you will have to use a scan tool and perform electrical checks to properly diagnose the compressor as being faulty

[@JesusSanchez-ee7re]

My just blows cool when I drive over 40 miles,, any suggestions Jim?

[@WoundedEgo]

Fans?

[@slayer666790]

I have the same problem, my condenser fan works, I get ice cold air at night when its around 80 degrees, but during the day, when it's 116 degrees outside, I can't any, maybe a bit of cold air while I'm on the freeway. I checked the relay and fuse, both good...I'm stumped....plz help...you really know what you're doing with AC problems..

[@slayer666790]

Also, my compressor clutch is engaging, but, not cycling on and off and nobody can tell me if that's normal? I'm also getting water dripping from a hose underneath the Honda, but I'm pretty sure that's called condensation??

[@Bidenvoterguy]

Hiw much a job like this cost

[@TheBgred1]

let me start off by saying, I fix my own cars, but no nothing about A\C systems. question for ya, no visible leaks on my system, the compressor comes on, and stays on, doesnt cycle off, according to the gauge on the refill can, systems full, all the fuses and relays are good, the actuator door inside the car is switching, but no cold air, seems like most youtube vids I look at?, only adddress a major leak, or a locked up compressor, which I dont have, Ive googled and watched so many vids and they only address a leak or like I said, a locked up compressor, or clutch not engaging, what else should I be looking at?, not knowing whats wrong is driving me nuts

[@jimthecarguy]

Does the ac compressor turn on?

[@TheBgred1]

the clutch engages and spins, but doesnt bog the engine at all like the compressor engaging normally does on cars

[@DriveShaftDrew]

customer is happy al;l that counts

[@victorleonard7087]

Im glad my accumaltor is made out of aluminum and its on the firewall.

[@jimthecarguy]

You would think that at least the manufacture would have left it open to air so it could drain.

[@ChicagoDoItYourself]

Agreed just a bad spot.. .. probably saved a foot of hose or two :P

[@steveg5576]

Another Northern Car....I said to myself... Steve in NC

[@drm315]

That battery needs to be replaced, it's leaking all over that corner of the car.
