The fan control for my heat and air only works on high . Anyone know
what might be wrong and how to fix . Thanks

It is the resister assembly loacted under the hood on the passenger side of the firewall....up high. Pull the wiring connector. Two screws hold the resister assembly on. They can be purchased from the dealer. They seem to fail often.....resistors and or connector seem to melt open. They high speed is wired direct....not going through any resistors. Thats why it works on high speed.

It was the resistor - had to replace the plug too . They were actually rusted together . Made sure i put a liberal amount of die electric silicone on the inside and outside of plug . Thanks again .
