My 2000 Sienna's front A/C fan is not working properly. There are four fan speeds on the dial and the first three are not working (no fan movement at all). The highest speed works so it is not the fan motor. A/C is working fine and the Rear fan is working fine too.
My guess is to change the Front A/C blower resistor. Or if there is some other possibility? Thanks for sharing your knowledge.
