Hello and Welcome-

My name is MIKE - Im happy to help you ..

If the resistor is ok - and the fuses etc - and you have power to the motor via the resistor...and the motor works when tested - that does tend to point to a switch fault.

These are quite a simple straight forward system on this Sprinter - so check the circuit to be sure as above.

Generally when a resistor fails, the heater blower will work on the highest setting only - IF thats the case- the resistor is at fault.

If thats not the case - and you have separately powered the motor and it works ok, then testing the circuit you must have no power going through - that then points to either a fault in the wiring / connections or switch yes - that would be the next area to check / to sort this out for you.

Best Rgds, MIKE.
