got a 2000 clk 320 and the cooling fan doesn't run, even when the engine overheated till the coolant boiled and steamed (that's actually how i realized the fan never worked since i bought the car couple months ago). the clk's onboard computer doesn't indicate any malfunction, all fuses are checked and good, nothing showed up even on a diagnostic computer in the auto shop. the shop owner told me i need to replace the thermostat but i don't think that's the source of the problem.

i've heard there's actually a fuse on a relay that controlls the fan on some mercedes models but haven't check this yet on my clk.

any other suggestions from any of you guys here??

Hi ooisper,

Welcome to the forum! I've moved your thread to the Tech Help section, where there's plenty of excellent advice.
