Heater problem
1994 Chevy Lumina 6 cyl Front Wheel Drive 189000 miles

Heater motor only comes on occasionally. The rest seems to work fine: ie controls that switch between modes. Ive checked the motors and cleaned up the relay contacts. What am I missing here?

Hi:
Did you check for power to the motor when it isn't working? Also, a common cause of motor failure is the blower motor resister. You may want to check that.

Let me know what you find.
