00 Super Duty Fan Problem
Having a problem with the blower speed. Only blows on high. As soon as you move it below max it blows very little like its on low nothing inbetween. Anyone know what could cause that?
Thanks

'High speed only' points to the blower speed resistor block. Don't know what your vehicle spec's are, but most trucks have them mounted under the hood in the side of the blower case. Follow the wiring from the blower motor plug and you should end up at the resistor. It's a ten minute, $20 fix.
