Heater problem
1990 Plymouth Acclaim 4 cyl Front Wheel Drive Automatic

I checked the fuses and all are good but the rear defogger doesn't work and the heater blower doesn't turn on. They both stopped working at the same time so I assume it is either a connection or a relay. I do have a repair manual and just need to know where I should start first.

I would start by checking to see if the blower motor has power when you turn it on. If it doesn't, go to the blower motor resister, the relay then the switch.


Let me know what you find.

PS: I don't believe the two run on the same circuit.
