2003 F150 Blower Motor
I have a 2003 F150, the settings on the blower motor switch are Lo, and Hi with two marks on the switch between the Lo and Hi settings. The only fan speeds that are working is Lo and High. When I set the switch to any of the marks between the Lo and Hi settings the fan only operates at low speed.
Is there something wrong with the switch or is there something else I should check first?
