How to access wiper motor on W124? - PeachParts Mercedes-Benz Forum

I'm planning to remove my wiper motor/transmission and clean and lube it, and lube the blower motor bearings with ATF while I'm in there.

I've seen great writeups here, complete with pictures, of how to disassemble the wiper transmission and also how to get into the plastic clamshell to get at the gears.

What I can't seem to find anywhere, including the repair CDs, is exactly how to get off all the air grill parts to get at the wiper motor. The manual refers to that job as "83-140" but neither my CDs nor paper manuals address this.

Could someone who's been there kind of walk me through this please?

Thanks!

Steve, the two lower trim panels on the bottom of the windshield just pry off. You will then see 4 screws holding the two side drains on. There should be two white horseshoe clips that tie the drains together underneath on either side of the wiper. Take the top weatherstrip off that surrounds the drain area and you will see two screws down low to get the screen off. Take the trim off the wiper motor itself,,, the 4 small screws. There are 4 nuts and one clip holding the wiper assembly in place,,, 2 on the left, one under the windshield on either side of the wiper, and that clip in front. As you lift the assembly up you can disconnect the wiring from the motor. Piece of cake,,,,, if I remembered everything. Then you can access the blower motor by just unclipping the cover.

Perfect! Just what I needed.

Once the weather warms up, now I have the confidence to tackle this job.

Thanks!
