Heat/ac fan speed
I have a 1999 Explorer Limited with automatic hvac. The fan sometimes
works but sometimes I need to put fan speed on max to get the fan to
run. I live in Florida so I don't use heat often but i believe it had
the same problem with heat. On occasion it works fine: Start engine, fan
comes on hi then reduces speed as cabin cools (heats). Other times the
only way to get air movement is rolling the fan control to hi/max.
Can anyone point me in the right direction?
