R129 - Window wiper gets stuck

[LeaUK]

Ok - on to the next new problem....

Anyone experienced stuck wipers? Intermittent used to just get stuck occasionally, then kick start itself again and operate correctly, however now intermittent just fails.

Symptoms are that the blade just stops in the most odd positions across the window, and for each wipe will stop in a different position. Often intermittent just stops altogether.

Also, the blade fails to find the park position - and I think this is my clue. I have to time the use of the wiper switch just right!

There are two 'modules' that control the wiper blade N10/2 (which sits in the black box above the fuse box) and the K26 relay module, located just below the blade somewhere.

My suspicion is that the park sensor in the motor assembly is failing such that the module 'thinks' the blade is parked when in fact it isn't OR that the relay driving the motor (K26) has carbon'ed contacts.

Has anyone else resolved this before?

Cheers
