Wiper Motor Repair

Hey All Again

98 528i e39 wiper motor quite working... junk yard wants $100 bucks and no warranty.

Is it possible to repair these motors? Are there any know issues with the motors having a broken wire or something inside that we can fix?

Appreciate all input

Jody

1. Check the transmission, this part may go bad too.

2. Used wiper motor is about $50 on ebay.

3. Open the wiper motor, usually the brushes go out. Go to local hardware store (Ace) and buy the brushes for $5.

Sure it's the motor and not a loose fastener?

wiper motor removed and cleaned

pleiades,

I tested the motor while mounted and got no response. I took it out and tested it on the bench, got nothing. So I took the motor apart in the inside was rusted from water intrusion.

Cleaned, scraped and flushed with contact cleaner, air dried.

Reassembled and tested again, motor worked. I tested pin #2 and motor turned slower than on pin#3. It still didn't seem to be turning fast enough. IMHO. So, re-installed all parts and pieces on car, started and turned the wipers. They worked but were moving slower than normal, and this was on fast speed. After 30-45 seconds, they just stopped in mid stroke.

All help appreciated....its looking like I need a new motor,,,? right?

Yeah,

Normally when any motor goes out, provided it is not damaged by water, you can simply renew the brushes and move on.

In your case, water already got in, so there is damage to the winding etc.

The new wiper motor is PN 67638360603 ---> $300.

Search for used one on ebay ($44) or local junk yard.

A very good ebay seller is "quarrymotusa" in Florida. I buy parts from them. They specialize in used BMW parts.

Below is a whole thing motor + transmission for $45 + $15 shipping = $60 total:

Also,

You will need to find out how H2O got into your wiper motor.
Check the drains for leaves/debris; pour some water to be sure it drains down properly.
Avoid parking under trees if possible.

I didn't even think of taking pictures, I got focus on getting it apart. Sorry....good news? What you ask...I have to put the new motor in and will have to go through the process again, I'll take the pictures then..

Will that work?

Thanks
Jody
