#6 of 8 High fan/recirculate by buuba116 Jun 29, 2009 (3:45 pm)
My 2005 Canyon: With the air on, compressor running, everything cooling, when I press the recirculate switch, the light comes on but there is no change in fan speed and whatever air redirect is supposed to take place doesn't. That is---press the recirculate switch and nothing happens. Could this be a relay?

I have islolated a problem with a nonfunctioning blower motor to the switch, I think. I took the motor out and jumped 12 volts to it and it worked fine so I assumed it was the resistor. Wrong. New resistor did nothing. I got a wiring diagram and it showed that on high speed the switch put the orange wire on the blower motor plug straight to ground. so I place the motor and the resistor on the floor board and stuck a wire in the back on the blower motor plug and grounded it. Bingo. The motor ran. Then I grounded each tap on the back of the resistor to ground and it changed speeds. Am I missing something or does the switch sound like the culprit? The wiring diagram does show a ground in the right side of the engine compartment but it is common to other circuits which are working. If you folks are in agreement that the switch is bad please tell me how to get to it. How do you get that panel off that holds the radio and swicth panel.
