Title: Rear wiper adjustment
Post by: Zuki-Girl on June 03, 2011, 02:20:09 PM: Ok back with a headache this time. My Sidekick didn't have rear wiper. So I got the stuff from a u-pull yard and installed it. Had power to the motor all three wires,but it wouldn't work. I pulled the cover off the commutator and it was corroded, pulled it out to clean the contacts and brushes. And put it back together again. The motor works now, but the wiper won't go full stroke and I think I messed up the timing of the tooth mesh. Anyway to get it back to normal park and sweep?

Another thing,with the linkage disconnected it travels fine,but connect it and it stop half way through return cycle. If push the arm a little it goes again,but will stop at same point. Should I just go ahead and replace the motor and relieve the headache?

Might have to.
