Being a novice AC guy and jack of all trades/master of none for 30 years, I can honestly say you did an EXCELLENT job explaining and showing everything as well as addressing the correct procedure for filling with details. Great work!
Never in my life have I watched a more informative video with such care for detail and common sense all in one package. If you are not some type of teacher for the automotive industry? You Sir are missing your calling. Thank You for your time and expertise explaining and demonstration. Hats off.
Thanks for the comment! I am not an instructor but have over 40 years experience in automotive, heavy truck and transport refrigeration repair and maintenance. When I get a chance to make a video I try really hard to do do it in everyday language for the “Do it yourself “ mechanic. Really glad it helped! Thanks again!
Great video, very informative & reminded me that my 2015 Tahoe has rear A/C. I've searched every line & every component up front with no luck so watching this gives me hope that it's leaking in the rear A/C section. Thank you again!
Great informational video. I'm not a mechanic, nor do I have the tools you used in the video, so I guess I'll need to take it to shop to get this done.
Just had my 2015 Tahoe lt rear evaporator changed at a dealer and the rear is still blowing hot air and they can’t figure it out. (Probably out of hours and done dealing with it for free). The lines going in are not cold underneath and no water dripping from the rear drain at all. Any help would be appreciated!
Thanks for the video! Is it basically the same process for the front expansion valve? ...where it can be replaced without taking the dash apart and you can get to it from the outside?
Yes it can, however you can purchase a block off kit to block of the back ac so that your front system will still operate perfectly, if you have an issue in the back but don’t really need the back ac it’s a good fix
Greetings to you, my dear brother But I have a question Did you use the high-pressure line to fill Freon? Why? Others object to filling using high pressure... and they say filling Freon should be using low pressure Thank you
Sorry this has taken so long but the answer is yes. You can absolutely recharge on the high pressure side as long as the the engine is switched off and the A/C is not operating. If the engine is operating and A/C is switched on the you must recharge on the low side only. If you recharge on the high side with A/C switched on and operating it could over pressurize the container and explode. Hope this helps! Thanks for watching!
Gotta quick question i already know now imma have 2 replace my whole ac system...i have an 04 srx 3.6 cadillac had it for 7 years I noticed my clutch was barely engaging so I assumed it was burned out which it was so I figured just replace the compressor boy what a mistake it lasted all of a month cool air front and rear now my brand new compressor is the clutch is barely spinning doing the exact same thing but not as bad then I noticed the compressor started smoking just asking do u think I have a bad expansion valve or some kinda block in the system
When you replaced the compressor did you flush the system? This sounds like the new compressor just had a catastrophic failure. If a compressor disintegrates internally the debris will contaminate the system. The system will need to be flushed before putting in new components. Expansion valve will have to be replaced too. Another thing is to add the exact recommendation of oil and amount. When adding oil to the compressor you need to rotate the compressor several times to ensure the oil is coating all internal surfaces of the compressor prior to installation. Then, evacuate the system and recharge with the exact recommendation or refrigerant type and amount. These systems hold such a small amount of refrigerant that the slightest amount either way could be detrimental. Hope this helps. Thanks for watching!

Very good video - comment from an experienced "non-professional" in Arizona !!!

Thank you again!
Rear evaporators can cause issues. They are sometimes a little tricky to diagnose but it’s definitely not impossible to do. Thanks for commenting!
Is there a filter inside the hi side line at the rear expansion valve?
Great informational video. I'm not a mechanic, nor do I have the tools you used in the video, so I guess I'll need to take it to shop to get this done.
Thanks for the comment!
you can purchase refrigerant with dye and a kit that contains a black light used to find the leaking UV dye.
Im not a mechanic, I do not own this car, TH-cam just decided to recommend it to me.
Great video, Though!
LOL! Thanks for watching it anyway!
You Sir, are the best teacher ! Thanks so much

Very good description
Thanks for watching and really appreciate the comment!

correct
if the rear expansion valve is cloged or not working well , does it effect the cooling in front ?
i have 2007 denali .
Yes it can, however you can purchase a block off kit to block of the back ac so that your front system will still operate perfectly, if you have an issue in the back but don’t really need the back ac it’s a good fix

@@lizardjump995 thanks I didn't install it.....sadly it was the dealership
Hopefully the dealership did all these tasks which in any case should be under warranty through them.
you missed one step. the filter screen in the high side line at that valve
Thanks for that reminder!
Did you have to add oil?
I did not add any oil. Only lost a couple drops when removing the valve and didn’t to overfill the system.
Typically don't have to add oil unless you are replacing the compressor
How do you get the panel off
Hello…..which panel are you talking about specifically?
