Wiper Trouble

There's usually loads of wiper threads but when I need them, they're all gone!

1998 T202

Wiper seems to falter when it reaches near vertical during it's sweep in either direction. It sweeps fine from horizontal to around 45 degrees then struggles through the vertical section but travels down to horizontal OK, it's the same coming back again. It's as though there may be some resistance half way through it's sweep. Windscreen is clean, what do I look at?

I can't see how the cover at the base of the arm comes off so I haven't seen inside yet, not that I know what to expect when I get there. I don't know how this single blade with lateral travel idea works but I'm not completely useless and don't mind having a go. Is it something I should avoid checking myself or is it safe to have a quick look?

Thanks

You need to take it apart, clean and grease the linkage. The screws are only revealed when the wiper is in vertical position. So start the wiper cycle and turn off the ignition switch... then manually move the wiper to vertical position.

It's now working fine.

Actually there was no need to remove any screws, the cover is only clipped on. The cover cannot be removed unless you remove the arm from the shaft, but it's clamped on and the clamp is an integral part of the arm tightened by a single bolt. Although I removed the bolt, the arm remained fast and I was not keen to stress the clamp as it's cast - my history would confirm that it will snap before it becomes loose. However the cover can be lifted and moved far enough to clean & lube the shaft that was really dirty & dry so all's well.

I heard rumours that the wiper mechanism is often messed up and would need to be reset by the dealer but this job seemed straight forward enough, thanks for giving me the confidence to try.

This is what I do when the wiper of my W201 starts misbehaving. My wiper has a small rectangle cover near the base of the arm. If opened the stem is uncovered.

I turn the ignition on, turn on the wiper and turn off the ignition when the wiper blade is in the farthest position (some 45...60 degrees). open the rectangle cover and put some grease or heavy grade oil on the stem. That makes it.
