W126 headlight motor

[h17n dj]

Evening all,

As the title suggests, is there any way of repairing the headlight wiper motor? My drivers side has just failed. Tried giving it a gentle nudge, but nothing!

All help appreciated

You sure that you're getting power to it?

The passenger side works. And also the washer part is working. Just not the wiping.

Put a volt meter to it and see it you're getting power. They're all different circuits. Alternatively, take a power tool battery and a couple of wires and put it directly to the wiper motor to see if you can trip it.

The shaft of these motors is often seized due to water ingress and corrosion causing the motor to burn out. You will have to remove the headlight to repair/replace it. this w124 system article may also help ? but first check the electrics as recommended above.
