Possible reasons why my Mercedes c300 air conditioner does not blow air at all.

Hello, if there is no air blowing, there is either a problem with the climate control system itself in that it is not commanding fan speed, a problem with the blower motor itself, the wiring and connectors to the components including the blower motor, the blower motor resistor, relay and or fuse. Hands on testing is needed to figure out what's going on. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
