Heater Problems

[buckshotmudder]

I had the heat on high today and it would cut out occasionally and then it completely quit. The light still comes on if you turn the ac on but no air will come out. I have replaced the blower motor not too long ago so Im thinking that the switch itself is bad but it does still light up. Any ideas?

Does the blower work with the switch in any other position like medium? Run 12v to the blower motor and see if it works? that will give an idea if its the switch or the motor.

yeah im gonna try that tomorrow.. i bought a used blower motor off a member on here probably 2 yrs ago so that might be the problem.. sometimes after i turn the vehicle off and then turn it on, it will not blow heat no matter what position the switch is in.. then after ridin down the road, itll just come on sometimes by itself

i would start by checking the power conections then see if your fuses are ok. maybe a loose power wire or ground? just some thoughts.

Yea thats what happened to my power windows, they kept cutting off and on while driving. Turns out I was kicking the fuse panel everytime I pushed the clutch which eventually shook the circuit breaker from its housing.
