A/C doesnt work in my 91 Q

Post by **mrtheronj** » Sun Apr 23, 2006 7:21 pm

I have a 1991 Q45. The air doesnt work and Im wondering if anyone can offer suggestions. The compressor comes on. It takes freon. The pressure gauge for the freon reads that it is fine. But it just doesnt get cold. The fans are blowing fine. Also, the "orifice tube" was changed but that didnt help either. Any suggestions???

When was the receiver-drier last replaced? Did you over oil the system?

By "doesn't work" do you mean no temperature drop at the vents - or some but just not enough? A meat thermometer will tell you a lot...

What does the built in AAC diagnosis report [see FSM]..........air mix door stuck on heat? Swap AAC display module?
