Dash fan only works on High Setting

2001 XJ of a friend I was wheeling with this last week had a dash fan failure. His fan now only blows on high speed, lower speeds dont work anymore. (it does turn off normally). It was fine just prior to the fail.

Where will be common failure modes on this problem? switch, fan resistors (I assume this uses resistors in series to modulate the fan speeds) connectors, etc...?

What is the trouble shooting routine on this?

Thanks!
 
Most likely the blower motor resistor.
 
Yep, first thing would be to replace the blower resistor. They're cheap, and easy to access.
