Thread: Motor wiring help!!!!

Tweet

Ok - need help - got a few late 90's ac delco motors - only problem is there is 3 prongs atop the motor and 6 down on the base of the gear housing. What prongs activate the high and low and ground (common) to make these work? Any help is appricated. Thank you....

I saw a part number on the label in the second pic - have you tried googling the number?

yeah, no go for a diagram

You need to remove that piece and below you will have two simple wires you can connect to a power source. I use a battery charger and a dimmer switch to control the speed. Works great on my rocking granny.

thanks for the help...I tested and the 6 do nothing...just the 3 connectors to power it up...thanks again guys..

I love a good puzzle!

I found that this wiper motor looks very similar to the ones you have:

Then I searched for 1997 Chevy Monte Carlo wiring diagrams and found this:

So it looks like the three pin connector is your motor connections:
A = High Speed
B = Slow Speed
C = Ground

You should be able to use a ohm meter between the case of the motor and the pins to determine which is C and then infer the other connections from there.

The other connector is the parking switch and intermittent wiper electronics.

Thanks brad!!!!!
