The blower fan on my 2003 GMC Sierra works in the 3-4-5 positions only. 1-2 I feel no air movement. Is that the switch or the motor? I
believe that if the motor works, it works and the speed is controlled by the variable resistance in the switch positions. So my analysis
is that the switch is bad but wanted to be sure I'm thinking correctly. Your thoughts?
