Rear Wiper Motor Replacement
Posted 01 January 2004 - 06:03 PM
Since it's a holiday and the yards are closed and I have a hole in the rear window where the assembly should be, I thought I'd take the motor assembly apart to see if I could fix it.
After disassembling the original and the replacement I've concluded that these must all fail the same way; Corrosion sets in right around the shaft where arm connects, and when it gets too cruded up to turn the motor starts breaking teeth off the plastic gear it connects to.
Both had about an inch of teeth missing, and both shafts were set up tight in the housing.
If the plastic gear was available seperately, these things wouldn't be that hard to rebuild if you can get the shaft freed up. The rest of the components are metal.
Has anyone had success installing junk yard wiper motors? What's the chances of finding one that won't have the same problems?
What do you think a brand new one will cost? As always, all opinions appreciated, thanks!

It might help to spray some lube down the end of the shaft housing after the cover is off. The 2 I had apart where both corroded in the first half inch.

I told the guy to pick the OB with the lowest miles (they had 10 98s to choose from!). This version looked updated with a different wiring setup and the screw at the end of the motor shaft wasn't there.
It works, turns smoothly. I hope it last a while.
