Dennis Detweiler Posted June 21, 2018 Report Share Posted June 21, 2018 The heater motor wiring wasn't connected when I bought the car. I pulled the motor and it won't run by connecting it to the battery. It has two wired coming out of the housing that were missing insulation. Maybe it shorted out and someone just disconnected it. I pulled the housing and spliced new wires. I connected it to the battery post and it's lifeless. I tried switching + and - and still nothing. Tried grounding the motor casing and nothing. It doesn't smell burnt. The brushes look to be making contact with the armature. Any guesses or direction? It spins freely. Quote Link to comment Share on other sites More sharing options...
soth122003 Posted June 21, 2018 Report Share Posted June 21, 2018 If the motor spins freely, continuity checks are in order. Clean the armature,. It's basically a DC motor, If you can pull the motor casing/housing, check the condition of the windings, wires, and make sure they are not grounded or shorted.

Dennis Detweiler Posted June 22, 2018 Author Report Share Posted June 22, 2018 The brushes are shot. Probably two chances of finding a new set, slim and fat. There's a used motor on ebay that looks identical, but has a different rear mount. I could probably grind off the rivets, remove it and put mine on it? Mine bolts on.

Jerry Roberts Posted June 22, 2018 Report Share Posted June 22, 2018 (edited) Be careful of the insulation on the wires on the used motor , it might not be in very good condition either . Edited June 22, 2018 by Jerry Roberts Quote Link to comment Share on other sites More sharing options...
Dennis Detweiler Posted June 22, 2018 Author Report Share Posted June 22, 2018 (edited) I can see by the photos that the wires need attention. The seller stated that they need replaced. I may be able to slide some heat shrink tubing down into each wire and not have to open the motor. The insulation on my old motor was bare on both wires down into the motor. Plus half of the wire strands were broken. Someone had taped it up, but it likely shorted out and the reason it was disconnected. I'm just going ahead and taking a chance on this replacement motor on ebay. The seller has perfect feedback. He also stated that he tested it and it runs.
