Cooled seats work but ac does not

[Rwsmit17]

I just bought a used 2015 GMC Sierra 6.2L with DoD delete. AC blower is loud but air is pushed through the cabin just no cold. but the cooled seats operate just fine. any ideas?

The cooled seats aren't actually cooled but ventilated using the cabin air. I'm willing to bet you have a leak in your condenser and lost all refrigerant.

Ya, the systems are not the same, completely different (as @m3n00b has stated). You will need to take it in and have it serviced. 

 

My AC guy says that you can lose up to 2oz of refrigerant each year, most though lose around .5oz per year and once you get to that tipping point where the low pressure switch gets tripped, it will need to be serviced.

Welcome to the site.

 

Your seats in the 15 are actually cooled, they started the ventilated system in the 16 models, but not tied to the AC at all.

 

My guess is your condenser has failed, very common problem on the early model K2's. Tons of posts here on the site about it.

thanks all for your help!

Update: so I understand this is shade tree mechanic kinda stuff but I believe my compressor clutch is not activating. And we brought an ac repair refrigerant and if anyone has used one it basically says that it can not tell if the system is full or out of refrigerant and to take it to a professional . Well, I’ll be damned
