I'm trying to pinpoint the problem but before I go any farther I figured I'd ask first. I've changed the blower motor resistor, bench tested the blowerror motor it's self and wired a new plug that plugs into the resistor and still no fan speed what so ever when I'm turning the heat on in the truck. Any ideas? Thanks

 

Checked the fuse yet?
Or the relay?

 

well.. this is this first time in my life the fuse was not pushed in all the way for what ever reason. Can't believe I didn't check it, automatically thought the worst haha thanks man.

 

Funny you should mention that...
I have a certain fuse in that little panel that doesn't like to stay in either. I had to give the prongs such-an-ever-so-slight bend.

 

yep, it was loose fitting, so I did the same thing, dodge life... haha
