I have a 1993 cadillc Deville. On my AC no matter what buttons I puch or anything my ac will not work. You can hear like somehting is opening through the vents or something to that effect but no Air. Nor even on Defrost of Heat or nothing. Im not sure if this helps but when the car is on in the middle of the engine just left of the belts and a liitle up There is this hissing Like Air being let out of a tire type. Im sure how else to put it. Im not really that good with cars but Want to learn so I can restore this car. Thanks in advance. Robert Miller

See if you can scan codes, push off and warmer on the heater controls, at the same time, with the key in the on position, should start out with 8.8.8 and end with 0.7.0.

no F codes, f codes are body codes

E codes are engine codes, and I dont see any AC codes

well its communicating so try to erase the codes, do the off and warmer thing and after its done going through the codes push I think the inturnal 2 buttons
