Did the dryer come with a new pressure switch?

What are the radiator and condenser fans doing?

Is the heater still working?

Any codes coming up via scan?

What about HVAC DTC's? You can check those yourself.
Retrieve HVAC DTC's: Link
Have you checked or replaced the power transistor?


There are a number of possibilities. You should buy a Helm's manual and a DMM.

You don't have to have a code reader for HVAC DTC's, you can do it as the car sits. Follow the link he gave you.

One of these will prove to be useful.
