Usually if you can smack the dash, kick it under the dash, run over a bump or dip in the road and it comes back on the fan motor is worn out and the brushes intermittently make and break contact with the commutator. Sometimes they work for a long time others they are hard to get to start again.

Based on your description I can't tell if when you were checking pin C if you were reading through the resistor pack or not, I am also not familiar enough with this car yet to know all the information you are looking for without reading the schem.

here is the schematic that I just googled....

please understand, the motor is fine and the problem is with the wiring. There is no continuity between the fuse location to the actual wire terminal pin C of the connector that plugs into the resistor pack. I have no components plugged in at the moment and just metering wires. So there is a break somewhere in that wire terminal to the fuse location under the hood.

i just need to take some extra time this weekend, pull the glove box and see if I can somehow follow the red wire back from the connector pin C back to the fuse panel. If I can't easily find the break, I may just have to run a new wire and call it a day. My hope is that I pull pin C from the plug under the dash and find that the metal pin is just not crimped real well to the wire. It may be helpful if I can get a probe of some kind that can pierce the wire insulation and allow me to check for continuity back to the fuse until I find the break. This might just be one of those issues that there is no simple answer for other than just repairing the wire.

ive seen lots of posts and videos on the motor and how these can have problems. I can assure you, mine spins fine, has not drag at all and runs perfect when connecting directly to a power source. As difficult as it may be to find the wire issue, I guess I need to look at the bright side and that I don't need to spend money on a fan or resistor pack.
