My radiator cooling fan seems to have decided it needs a vacation & only works when it feels like, which is quite rare nowadays

Being hands on & ready to tear it apart; was wondering if this is repairable rather than replaceable, hopefully saving a small fortune!?

Have stripped it down as concluded the controller module is at fault, as is usually the case.

Was wondering if anyone has a defective controller module lying around & not needed? If successful will share the info as presently, the only solution is to replace the whole fan assembly.

It might be of use; can you check the part number on the module?

885 000 764

It should be a TEMIC 850W

I had this happen on my W203. I ended up (as you have) diagnosing to the fan controller). Water ingress had toasted some components. I bought a second hand unit from Dronsfield’s in the UK. THIS WAS A COMPLETE FAN, shroud & controller.

That fixed it.
