I drove my quadcab 4 days ago and the heater was working fine. Today the blower will not come on at all in any position. I checked both fuses in the cab fuse box and they are fine. Any ideas where to start? Thanks for any help.

 

Welcome to the forum Mike.

Check the resistor and harness for damage.

Passenger side foot area, look up.

 

The blower motor resistor is pretty cheap and found at most auto part stores.

Thanks for the replies. I replaced both parts. The resistor was fried.
