A/C and Heater BOTH not working
1996 Dodge GrandCaravan SE, 3.3L
as stated, both my a/c and heater do not work. my brother in law took the car down to LA to disneyland and a few days after he came back, it just didn't work anymore. my husband thinks my brother in law had the a/c on full blast to and from LA, could this have burnt something out in the car?
my husbands scanner came back with a 'A/C clutch control relay' but then afterwards, it changed to a 'radiator-something'
we changed the front relay, changed the fuses, grounded a battery and checked the blower, it ran, but when plugged back in, it didn't work. any suggestions?

So it doesn't blow cold, sounds like the a/c compressor doesn't engage. What doesn't work with the heater?
The "a/c clutch relay control circuit" code means there is either a short or an open in the a/c clutch relay control circuit. Here is a wiring diagram for the compressor.
basically, if you can ground pin 64 of the C2 PCM connector and the relay clicks, you have a bad PCM.
