Front heater doesnt blow air but the back heater works
I have a van. I have a heater for the back of the van
and a heater for the front. Both have been working
great. Today, the front heater is not coming on but
the back is working just fine.
If it doesn't blow at all, could be a bad motor, relay, switch or fuse. If it only blows on high, then it may be the rheostat (resistor). Need a test light to see if any power is getting to the blower motor.
