How to Replace the Cabin Fan Resistor on a Smart Fortwo

Model: Smart Smart 451 - Years 2007-2015
Part: Blower motor

To replace the cabin fan resistor on a Smart Fortwo, open the glove compartment and remove the plastic covering located under the central tunnel on the left side; use a lever to detach the covering under the dashboard. Open the glove compartment and unscrew the securing screws around the perimeter with a screwdriver. Once this is done, pull out the glove compartment and disconnect the power cables. Remove the fan resistor from its housing; insert the new part into the filter holder and reassemble all components of the tunnel as they were disassembled earlier.
