'76 FJ40 wiper motor (1 Viewer)

[Swymmer]

Hi again, ya'll!
When I bought my FJ40 a year ago I found that someone had severed the wire harness to the wiper motor. Don't know why but suspect there was something wrong with the motor or the switch. Anyway, is there a trick to testing the motor? When I ground the unit and touch a hot lead to the individual contacts within the connector on the motor... I get nothing. Do more than one of the wires need to be energized at the same time? Or, do I just find another motor? Would love some help! Thanks.

You might need to pull the motor apart and clean it. Refill the gear housing with silicone grease. There are a few threads with tidbits of info but I don't recall a great step-by-step. Once rebuilt make sure the windshield frame has a solid ground to the chassis. I ended up running a dedicated ground wire into the glove box because I was getting intermitted ground through the windshield hinges. Also think your wiper switch needs grounded to dash. So if you have fresh paint you'll need to scuff or run a dedicated ground wire.

‘3/76 Wiper Motor wiring......

So I recently acquired a wiper motor and am wondering if any of the experts can tell me what wire is hot. Blue wires, one is red, one is black, one is yellow and one is just plain blue. Motor not working. Pics below: Also what size and pitch screws are needed to mount to windshield body...

Apply +12V to the solid BLUE wire, then ground either the Blue/Black wire or the Blue/Red wire for hi and low speeds. The Blue/White wire is for the park circuit.
