My heater stopped working a couple days ago it was running fine then stopped what could be the problem?

 

Could you post a little more detail?

Is it not blowing at all? Just on high or low? Blowing only out of the defrost?

First place would be to check the fuses...

 

my first guess is blower motor resistor

 

My second guess is blower motor

 

I feel heat out of the vents but no push... checked the fuse its good it started to work again one day and then it stopped

 

this may sound dumb but pull the unit out and check if its plugged in, mine quit working one time and it turned out it came un plugged when i put it back in after installing a new radio deck

 

Have you checked your ground wire ?

 

whos Heather?

 

Amazing how helpless some people are

 

Pull dash panel and remove the heater-A/C controls.
Check the wiring to the fan switch.

The switched have a tendency to melt and or short out.
It will be very obvious when you pull the unit out, there will be bubbled plastic pushing out of the wire "ports" of the connector.

I have replaced wiring and switches on 3 Cherokees so far.
