I have a 351/4x4/standard/air. The blower motor only works on hi,,,and the wipers come on when you put the turn signals on. I replaced the blower fan switch and checked the motor. All work. Is there a resistor pack for the voltage drop to the fan that I am missing???
I had a similar problem on my '94 F-350 and the turn signal nonsense went away with a new flasher. As for the blower, it sounds like there is a bad connection somewhere, probably nearer the motor as you already replaced the switch.
My '94 F-350 is currently only letting air vent upwards (defrost) regardless of where the setting is. Anyone know where a map of the vacuum lines can be found so I can trace possible vacuum line issues? My Haynes manual doesn't have one.
