"Jerry rig" a small gauge wire that you can put in various connectors---like the blower motor lead, the switch and maybe even the fuse panel, and tie that to a light so you can see where you are losing power. Also the blower has a ground pigtail.
Don't discount the motor could have a problem, like, dry bushings
Thanks for the reply 67dart. I’ll give that a shot. I honestly wouldn’t be surprised if the motor is shot. It’s original to the car and hasn’t run in a long time. Thanks again.
