2007 Suburban 1500 all vents blowing hot air while AC is on.

Customer Question
2007 Suburban 1500 all...

2007 Suburban 1500 all vents blowing hot air while AC is on. Compressor clutch is engaging with no real noise. There is freon. None of the lines going through firewall get cold either.

Mechanic's Assistant: Has the clutch been slipping? Are you having any trouble shifting?

Really?

Mechanic's Assistant: Are you fixing your Suburban 1500 yourself? What have you tried so far?
