Hi, I have a 1998 K1500 silverado. Having problems with my blower motor. It will not work. The blower will not work. It used to only work on High setting but it was intermittant. Now it will not work at all. Is this a possible relay problem? If so were is it located???

I do have bleed air comming out of the vents if i am driving.

 

Anybody have any ideas?

Thanks

 

test the fuses, power going to the motor, then behind the dash is the blower motor resistor, that should get you started
