blower motor switch not working correctly
I have low speed on the first three positions and high on the last one, high is too high and low is to low 
Is this a common problem? do I just need a new switch?

Gary,in this circuit is a resister block that the pwr to the motor goes through it usually is the culprit . to trouble shoot it ,you should get a wiring diagram of your truck.
What yr is the truck?

ok, its not the switch. Turns out I just have high speed not low speed, it was just the little bit of air blowing through at speed. Anyone know where the resistor pack is at? Is that what controls the fan speed?
