C250 4matic - W205
W204 C200 Cooling Fan Wiring

Hello all,

First info:
2148 ccm with 100kw manual transmission from end of 2007th.

I bought used and damaged C200. Not that much damaged but couple of parts needed to be replaced. One of them was Radiator fan.
After everything done, firstly fan wasn't working at all. After checking wiring I saw it was damaged in a crash and I soldered it again. Now it's constantly working.

My question, does anybody have wiring schematics for this model so I can double check if it's done properly? I don't want to go to service because they will rip me off. I just want to do it by myself as I did everything else.
If you need some more information, please let me know .

Thanks in advance.

Thanks! I'm currently trying to fix my fan - does not come on at all. I guess it won't be AC pressure switch, because if it was, the fan would be spinning non-stop all the time?

Cheers,

It should be like that. That it doesn't matter what switch is failing that fan is working constantly.

Try checking wiring, maybe it got damaged somehow or maybe connecting it to a diagnostic to read out errors.
