Posting for my brother, his truck is a 2001 reg cab manual 4x4 with 4.6 and auto tans. Truck has roughly 130 i believe on it, this moribg he had blower on high in defrost position about three miles from leaving his apartment he said he heard a POP and the blower quit. No burnt smells or anything he said. SO Im gonna check the fuse first after that what should i do? Is there a relay for the blower? And do the new trucks have a resister for the blower speeds? If so how do i check these parts?
Thanks

 

I got it, good thing for youtube
