Fix your blower motor speed control with this used OEM blower motor resistor for the VW MK1, part number 171905051B. This is the resistor that controls the fan speed settings on the heater blower — when it fails, you typically lose one or more fan speeds (usually everything except high). A very common failure on these cars and a straightforward fix.

Note: This is the non-AC version. Confirm your vehicle does not have factory air conditioning before purchasing.
