You can just pull out the fuse and see if the wire inside is broken. Buy one of these and keep it in the truck. https://www.amazon.com/gp/aw/d/B000B...wwL&ref=plSrch The yellow thing both allows you to test the fuses in place and the other end is a puller making it easier to get out.

This one has 7.5 amp fuses which the other one does not. Not sure of the brand though.

Yes, that is the plug to the motor. Put power across it and see if it spins. Best to look at a wiring diagram to know what wire is what. Looking that other side of the plug, the purple wire is +12V with ignition on and the green wire is grounded when the heater switch is on.

Thank you. Purchased. I noticed that numbers on the fuses don't match the numbers on the cover in quite a few cases. For example, the cover might show that it should have a 15 but the fuse that is installed is a 7.5 or a 20. That can't be good, right?

Ok, good to know. I will stick the new volt meter in there later today.

What do you mean by "Put power across it"? How do i do that?

Not sure about the mismatched fuses. There is one that was supposed to be updated from a 7.5 to a 10 but I forget what it was. A 10 in a 7.5 is probably ok. A 20 is not. A smaller amp fuse may blow, a higher amp one can cause issues. Are you sure you are reading the panel cover correctly? My guess is someone put in whatever they had when it blew, but you should put in what is on the cover.

Ok, I received my volt meter and tried it out. I got a 12v reading from the top left fuse (overhead light) so I know i was doing it correctly. I did not get any reading from the top or bottom fuse 4th from the left in the above photo which the diagram is showing as the fan fuse. I also tried the voltmeter at the plug to the motor and did not get any reading
