Ok... well I replace a DCCV because once in a while my pass. side would start blowing hot air. After the replacement it hasnt happened yet... both sides blow cold and warm air when needed and the temp. changes just fine... however... when set to cold my driver side is blowing cooler air then the pass side .. (maybe by about 2-5 degrees difference) when its set to hot the drivers will still have a little bit cooler air coming out (again about 2-5 degrees). Is there a AC thermostat? or do you guys think that it is going to be DATC? The difference in the temp is not that bad and I guess I could live w/ it but just checking. Thanks for your input.
