The fan motor in a Mercedes Sprinter van is located beneath the passenger side dashboard near the blower. Common issues include a blown fuse, faulty resistor, poor motor ground connection, or a malfunctioning speed control module. To fix the problem, remove the glove compartment to access the motor and resistor. Refer to the panel box diagram or the owner's manual for the blower's location. Before removing the resistor, make sure to disconnect the negative battery terminal. Use a flathead screwdriver or fuse removal tool to extract the relay. A replacement resistor can cost between $20 and $75 depending on whether it's an aftermarket or OEM part.
If your Mercedes Sprinter van's blower motor suddenly stops working, the likely causes include a blown fuse, defective resistors, a weak motor ground connection, malfunctioning motor speed control module, or a defective motor.
