Heater Fan problem??
I have a '91 F-150 and have noticed that the a/c heater blower only has the high setting. When I turn it down to any of the lower settings the heater turns off and does not blow. It also makes a grinding noise when I start to use it on the high setting. Can anyone help? Do I need a new motor? Thanks

87 XLT is right. If you only have the high setting, it's most likely your resistor. I just replaced my blower motor for the same reason. It would make this terrible squealing noise when I'd first turn it on but then would go away after about 30 seconds.
