blower motor

I pulled the factory AC from my truck b/c the compressor was shot. Won't get another one for a while. since I have took it off my heater will only work two of the power settings, low high and medium high. Low no longer works and high no longer works. Does anything with the AC system have anything to do with the heater? I hate to pull the hood to replace the motor but look like I may have to

Re: blower motor

whats a heater box? Basically all I did was take the AC compressor and hoses off and hooked everything back the way it was. It worked a few months ago.

Re: blower motor

Sounds like the blower resistor, and maybe the hi relay gone bad.

Re: blower motor
