alchresearch Posted December 6, 2010 Share Posted December 6, 2010 Alot of vehicles have a heater resistor which controls the different fan speeds.I dont have knowledge on your vehicle but its something to look at as these go brittle and break leaving the fan not working although in alot of cases only affects some speeds. The resistor usually sits in the heater casings. I'd go with this. Either the thermal fuse on the resistor pack or one or more resistors failing.
