Hello! The AC in my 2016 Suburban is not working. The front blows warm air, but the back blows cold air. Please help!!

Thank you in advance!

 

I trained as an A/C tech, but am a professional driver by trade. I am an expert with front A/C, not rear. That said if you are getting cold air in the back, that implies that
your compressor and the components in the engine compartment are working OK, but it never hurts to check the A/C pressures out. Must be a device on your Burb that sends air to the back, or it might be an expansion valve/orifice tube problem, or something in the dash controls not working properly. Not much else until the pressures are checked. Might even just need a can of R-134A, but you don't want to overcharge the system either.

 

Thank you for your reply! Going to have to go to the shop tomorrow and see what they say.

Thanks again!

 

Never add any sealers or refrigerant containing sealer !!!

And don't blindly add refrigerant; a real shop will pull out the refrigerant and weigh it, to determine whether fully charged. If low, then they can find the leak and determine system charge to diagnose. I recommend an independent ASE mechanic shop, not a dealership.

 

Yeah, if you can find a guy like Scotty Kilmer, who'd do well but lives in Houston TX,,I use a independent shop that has the hoist, lift or equipment that I don't have or cant mess with for days doing it myself. Yeah dealership costs are the highest, but they often do supply a longer warranty then indie shop so do.

 

Kilmer had some video of cleaning a catalytic converter with lacquer thinner. My brother in law thought this was a good idea, and Mrs. Cusser was there visiting; I told her to tell him "no" but she didn't want to get involved. So next day after she arrived home, there was a phone call:
..he set the car on fire
..the car set the garage on fire
..the garage set the house on fire
..the house was totally destroyed
..insurance won't cover all rebuilding and contents costs

This just happened in May.
