blower (no A/C) not working

[tarafied1]

I'm chasing down the electrical gremlins in my 72 Cheyenne. The PO had billy rigged a push button start switch and it seams the purple wire was just on the wrong post of the solenoid so it wouldn't start with the key. Switched wire to the correct side and it works normal now, that was an easy fix! Then I was troubleshooting fuel gauge issue and turns out it was just a bad fuse for the cluster.
So my heater blower doesn't work either, how can I test it? Does it have a fuse (the "Heat" fuse)? Probably something simple too... the lever is broke off but I can reach around and move the back side and the blower doesn't work.

Two things to check. Make sure that your blower motor is plugged in (under the hood), and yup fuse too. If this doesn't work that way, try running a hot wire from battery to your blower motor to check if it even works. Oh and double check your ground wire to the motor. I had that disconnected once and it stopped working.

Pretty easy system to troubleshoot.

I changed the fuse and no fix but I went to jump the motor and the wire was loose. Wiggled it around and pushed on it and then checked, it works!
