Re: Heater settings....
I recently removed my messued up air cond. system... would that cause this prob??? Ill look at the heater box and check the ohm on the resistors then the switch....

High speed = relay
Low speed = resistors

Re: Heater settings....
It's most likely the resisitor. It mounts on the side of the AC box with 2 small hex bolts and when removed looks like a couple springs underneath. Replace that and you should be good. Take it out and check if any of the springs are broken or burned.
