WASHroad Posted December 29, 2010 Share Posted December 29, 2010 '88 GL- My heater blower moter works on 1-2-3 but not on the high setting. Is that a bad switch or something else in the system. Link to comment Share on other sites More sharing options...

Tycho Posted December 30, 2010 Share Posted December 30, 2010 I inherited a car with non working 3 and 4 speeds, but the resistor was intact (and speed 4 doesn't use it anyway). Turns out that the fan was dying and the increased electrical load caused the switch to get hot enough that the wires had unsoldered from the switch. New blower fan + re-soldered wires -> problem solved. Link to comment Share on other sites More sharing options...
