1992 Cadillac Deville V8 Front Wheel Drive Automatic 85,000 miles
I have a 1992 cadillac Deville, with a 4.9 ltr v-8 engine, front wheel drive.
When I have the climate control on to the heat setting, and put it onto defrost, there is warm air blowing out the passanger side AND cool air blowing out the drivers side at the same time?
I have done the following:
Flushed the heater core 2x
replaced the thermostat
replaced the "t" restrictor vavle
checked the air delivery door behind the glove box
I do have an f48 code which means to service the air condtioning. Will that effect the heat?
have the same problem?
