1996 Explorer AC/Heat only working on high speed
I just bought a 1996 Explorer. The heat/ac only works if the speed is on high. Is
this a resistor or the blower motor, or something else altogether? Also, the
compressor was making an awful racket, so I charged it and that fixed the noise
but the AC still isn't blowing ice cold, but it is cool air at least. Thanks in
advance for any info and help
