Radiator Fan won't run

Radiator fan won't run, even with AC on, once warmed up, etc. This causes the engine to get way too warm of course.

The unit rotates fine by hand. My guess is that goofy module on the shroud is messed up. Anyone have an idea if that little unit can be rebuilt or replaced?

If not, any good sources on purchasing the whole unit for a reasonable price? The part number on my fan is A2205000293.

Thanks.

You need to replace the radiator fan motor. They dont usually sell seperately but u can find at junk yards for around $400. Also some on ebay. Good luck I just had this problem

You can use an S320CDI fan. IIRC they are also 850W motors. The motor and controller are hardwired together.
