Signs this switch may need replacing include a blower that won't respond at one or more knob positions, a blower that cuts in and out as the knob is moved, or a knob that turns without changing the fan. Blower problems can also come from the motor, resistor or wiring, so diagnose the cause first. If the switch is the cause, the 35806 replaces it.
