Heater blower problem

[Sadgrandad]

1992 525SE with a/c but not full climate control. Thanks to advice received here, I changed my filter and now get air in the cabin! Unfortunately, the fan is either off or on high - there's nothing from the intermediate switch positions.
Any ideas?
Thanks in anticipation,
Rod

Blower resistor package (R11) may have the thermal potection open. See picture.

instructions to remove resistor package, you should have a IHKR, so resistor should be in the LH Footwell, just up and right from the gas pedal, behind the carpet upper trimming. You are looking for component #5 from web link below.

Once removed, an Ohm meter should do it, just check proper continuity and ohm readings per the previous posted picture.
