Electrical & Lights, October 18, 2004
RepairPal Expert Overview
Our Quick Take:
The heater and air conditioning system fan is driven by a motor, which may lose power and stop working.
What Should You Do?
Please contact your Mercedes-Benz dealer. They will check to see if your specific vehicle is affected and advise you as to what to do next. Always have your vehicle identification number (VIN) handy when you call.
The HVAC blower motor may lose power because the fuse for the circuit may lose contact. This is due to a flaw in the plastic holder that secures the fuse that protects this circuit. If the fan stops working, you may not be able to clear fog and frost off of your windshield. If visibility is reduced, you could be at risk of getting into an accident. Dealers will install new blower motor fuse holders. This recall began during October 2004. The Mercedes-Benz recall number is 2004 070010.

ON CERTAIN PASSENGER VEHICLES, DURING THE PRODUCTION PROCESS OF THE BLOWER MOTOR FUSE HOLDER, THE SIZE OF THE ELECTRIC CONDUCTOR OF THE HOLDER MAY BE BELOW APPROPRIATE TOLERANCES.
CONSEQUENTLY, THE ELECTRIC CONDUCTOR OF THE BLOWER MOTOR FUSE HOLDER MAY DISSIPATE MORE HEAT THAN THE PLASTIC FUSE HOLDER WAS DESIGNED TO WITHSTAND, WHICH COULD RESULT IN OVERHEATING OF THE HOLDER AND DISABLING OF THE BLOWER MOTOR AND THE ABILITY TO DEFROST OR DEFOG THE WINDSHIELD IN COLD OR HOT AND HUMID WEATHER CONDITIONS. DEPENDING ON THE OCCURRENCE AND WEATHER SITUATION, DRIVER VISIBILITY COULD BE REDUCED, WHICH COULD RESULT IN A CRASH.
