The hot/cold air blower runs at settings 2 and 3 only - nothing at setting 1. I conclude that the portion of current limiting resistor used for the slowest speed has burnt out and that the fan is OK. But I haven't made any tests with a meter to prove this (yet). A study of the manual reveals a wire-wound 3 tap resistor buried in the guts of the blower housing.
Dismantling the lower dash and associated other heater related horrors does not appeal. Can I mount a pair of suitably rated resistors in a remote location and wire them into the fan switch? I was thinking of metal bodied multi-watt resistors mounted on some convenient chunk of heatsink (AKA body panel) - maybe on the bulkhead somewhere.
Am I likely to be completely wrong in my assumptions? How do I prove them? If it is a burnt out resistor, does anyone know the value or values of the replacement resistor(s)? I suppose that I could measure the value of the number 2 speed resistor and add one of the same value??
TIA
