Does AC Unit give trouble codes? How?

[capncash]

Does the AC unit itself give trouble codes? How? Or are they stored in main diagnostic unit?

Got AC totally restored last summer and now its blowing nothing but hot air?

[maxnix]

FSM has a diagnostic procedure. Any pressure readings? Clutch working?

[Q451990]

The self diagnostics that you can access through the controller give you information about the various mix doors and sensors in the system - but won't give you any information about the actual pressurized part of the system. Hopefully you have a warranty from the rebuild?

What happens when you skip a component/hose or two in the so called total restoration.............oem parts alone would run $2,200 to do a total restoration.

Hopefully just a bad o-ring leak.Watch out for hot/cold mix door failing in hot position common on 94-96 after a winter season.
