This is a Ford chassis, 32 foot unit. The front heater/AC fan works only on high speed. I changed out the switch and the resistor. No change. Still only works on high speed. I would really appreciate advice. Thank you.
I really hate to sound like a fool but I thought they only built clippers out of dodge and chevy.
