99 explorer problems with climate control

1999 4.0L SOHC Sport

It was hit in the front end a while ago and right after that began the problem

It will only blow on the highest setting (Fastest Speed)
It will only blow on Defog
No other setting will work
Hot and Cold Knob works

Checked all the fuses

thanks for the help!

Sounds like the blower resistor got damaged. if it only blows on high, usually the resistor is the problem.

not to be lazy or anything but where is the resistor located?

Look under the hood on the AC plenum. Tou will see a connector with 4 or 5 wires going to it. This is the resistor.
