Question about 2002 Mercedes-Benz M-Class
Dear Sir, I need a manual to fix the control of the fans of my car. I have ML 320 2002. The two fans (maybe for the AC, the fans are faced to outside) are always run even the temperature of the motor drop down to ambiant. The Electrician said that the computer (small part of it) must be changed. I don't trust him. Did there a manual for this, or would you help me what is the truth of the problem? my email is Elias.Daoud@dargroup.com (work) or email@example.com (personal) you can send to both.

If they are not shutting off then it could be a relay under the hood is bad. Change the fan and the air conditioning relay's.

whats happening is your a/c is putting an extra load on the engine. it happens with any car. that generates extra heat. it is possible that you need your coolant topped off, but chances are that your car would have overheated before if that were the case. what i would recommend is to first check to see if the coolant level is good. if it is, then get the car up to operating temperature and check to see if the cooling fans on your radiator are working. if not, it may be a bad fan, or just a fuse or relay. if that doesnt solve your problem, have the thermostat changed out for a new one. theyre pretty inexpensive. second, if you or someone you know has the know-how, remove the radiator, plug the fittings for the transmission cooler if it has any, and use a power washer to clean the radiator out. sometimes dirt can accumilate there over time and it wont let the heat dissipate properly. a coolant flush wont be bad for your car, but probably wont make your problem go away.

they don't run all the time only when the temp sensor tells them. is the car overheating?
