just hooked up wiper motor and it only moves the wiper blades roughly an inch and just keeps repeating. never had to mess with one before and thought maybe someone in here might know why?

i'll be grateful for any help on this

 

Id like to know too. Im trying to wire up a wiper motor in my 85, and it was doing that too.

 

well i think i figured out some of it tonight when i was at the shop. if you don't have any of the plugs for the motor it is alittle more complicated but here i go.

1. on the bottom of the motor there are two blades that are for power and ground only for the motor. So as you face the motor with it on the car the blade on the left is power atleast on mine, if not it will blow the fuse as soon as you hit the power.

2. now back up to the delay portion of the motor assembly. on mine the was a four wire plug on it and the gray wire will unlock the gear inside to allow the wipers to move full motion on what i believe is "high" and that is as far as i got. if you do not have the plug for this i believe that it is the middle blade of the three that are in line.

3. FYI, i went through 3 or 4 fuses trying this so you might want some on hand

hope this helps at least get you started good luck

 

thanks man, Ill probably mess with it when I have off work on tuesday. what did you plug into the bottom of the motor itself? what color wire?

 

i just used one plastic covered female spade connector(power) and one that was not cover in plastic(ground), its a really tight fight unless you got some smaller connectors.
As far as the color of the wire i just used red and black at the bottom of the motor and a small aligator clamp on the gray wire. I have not permanitly wired it yet, its just wired for testing. The other thing to mine is that i rewired the car with a universial painless 12- curcuit harness, so my wires are alot different than factory wiring.
