SOURCE: Thermador Blower Motor Not Starting

to check capacitor disconnect power to unit. remove wires coming from the capacitor making sure to note where they were connected. Using the ohms setting on your multimeter place one lead on each of the two post. Watch carefully and if the capacitor is good your meter will spike for a second then return to zero. IF nothing happens capacitor is bad. Good luck. Kevin

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

98 buick heater stop working


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

Low does not work, medium and high do


You probably cant fix it, this sounds like a multispeed blower with hi/medium/lo settings. You
can either replace the motor or connect one of the
working speeds to low/med or low/hi. or bump med to low and high to medium.

Sounds like you may have a bad blower motor resistor.  When they go bad, they usually wipe out all speeds except high.  But could knock out just one or two of the speeds.  It should be located near the blower motor.
