I just picked up the vehicle at body shop having the front bumper repaired. Turning on the air conditioner, no air flow is generated. I tried to remove "auto" set on driver side but this stays activated ( at least light is on). When I try override and setting fan to high directly, nothing. Defrost/heat/air all result in same result. Fuse/resister/switch gone bad or is the blower the issue? The sensor in the front bumber the issue? Any assistance is appreciated.

    The sensor in the front of the car is for outside air temperature it shouldn't stop the blower motor from working.I am not very knowledgeable in Mercedes but if you need test procedures wiring diagrams ect...... There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online

    Thanks for the response. SInce I wrote, it has worked on/off intermittantly. It seems to be the blower motor i guess. The link will be helpful to get the manual. Any idea where the blower motor is located on the car anway..hopefully a job not to difficult?
