Well, there's a thermostat, a fuse and probably a relay. Take your pick of which of these is not working as it should.
Also check if the fans rotate easily. On my 190E 2.6 the high speed fan froze and blew the fuse. Peter
and thermoswitch.
Also, don't know where you're located, but in most cars, its unusual for the aux electric fan to come on unless it's very hot outside and/or the car is stationary or in slow moving traffic. Normally the regular fan should provide adequate cooling. I had a problem once on my 300SD and part of the circuit was turned on by the A/C being on and the refrigerant temp at the radiator being over a certain temp. It was controlled by a relay. There's probably another part to the circuit that turns it on if the coolant gets too hot too.

Thanks for all the help on this one guys. I changed my temp control sensor and tested for current; the motor temp was checked and turned out to be o.k. A/C wouldn?t kick on fans because there was not enough pressure in system to activate it. Turns out there is a bad connection in the cluster and temp is reading erradic.
Because your auxillary fan clutch is shot. P.
