hello guys! i started my car today after a tranny ATF change, when the Radiator fan in my clk320 1999 turned on and wouldnt turn off.

So whilst still at the shop, he pulled some codes using STAR..it turns out the fan itself was defective, so he changed it with a replacement spare he had..

Still the radiator fan spinned like crazy sounding like jet engine, he also replaced the driver side SAM and a little rectangular metallic box on the driver side front bumper (sorry i dont know wat its called)..and nothin helped!!

no fault codes on the ecu (current or stored)..and the fan would turn of as i turn the engine off..thanks in advance guys..

 

No one with any help?:S

 

I'd be interested in this answer as well. This happened to me today. I have a 2006 clk500
