blower speed control works intermittently?

99 ford 250, the temp selector works and the positon lever works but the speed control knob works out of the blue intermittently. so it eaither has to be something with the blower motor or relay or regulator on motor? any ideas on this one.
thanks in advance

You need a new blower motor resistor. It's like $15 from Ford.

I got the one for my truck from the dealer, and the one for my Cavalier at Advance.

If it worked when you hit a bump, then your blower motor is going out. Happened in my Cavalier... it'd work when I went over a bump or had somebody kick it.
