Why does your 1998 Chrysler Concorde not blow out cold air when you put it on ac it just blows out air no matter what setting it is on?

Answer 1

I had the same issue with mine, it has auto climate control. Essentially the blower motor is not being told to turn off. The climate controls run through the PCM (power control module under the hood) which tells the blower motor to turn on and off and what speed to blow and where. Fix is expensive, so on mine i used a 30amp automotive relay to turn on and off the blower utilizing the 30 amp fuse in the drivers side dash. If you know how to use a relay, heres how to wire it.. pin 87a goes to one side of the fuse terminal, pin 30 goes to the other, so these two wires replace the fuse, pin 85 goes to switched power (accesory wire at ignition harness is black and orange 12 ga. wire) and pin 86 goes to one side of a 2 pin switch and the other wire from the switch goes to ground. I used a round 7/8" switch I mounted directly above the trunk release button under the drivers dash... Hope this helps.
