2006 Tukon Denali - AC need replacement

[Nick Dennis]

My mom has a 2006 Yukon Denali and the AC doesn't work at all. This is true for both the Front and Back AC controls.

We stopped by a auto repair shop and they added refrigerant to the system. This did allow the AC to work for a bit but after a day or two the AC no longer blew out cold air. We live in South Carolina an to have my elderly mom in this heat with AC is a bit too much for her. I would like to repair this system myself vs. having a auto repair or dealership service center do the work. She is on a fixed income and does have the cash for a full service center to repair the AC unit for the $1200 - $1500 they are quoting her.

My main question is this: I know I should start with the AC Compressor but would it always be recommended just to replace the Condenser, Compressor, and accumulator only? Or are there other parts that I need to consider?

My fear is that if I replace just the Compressor I'll find that the problem is somewhere else in the system.

Any recommendation for me?

Thanks!

Nick

If refrigerant makes the system work for a short period of time, it sounds like the compressor is good. The bad news is you have a substantial leak somewhere. Did the shop give any indication of where the leak is?

That's what I was afraid of. If the leak is somewhere else then I fear this might be out of my skill set to fix myself. I don't recall what the repair shop told her about where the leak might be located.

I may have a different shop look at it and see if they can pin point the leak.

Thanks!
