my temp controller on my 94 spins freely. the actual control behind the plastic spins all the way around.

 

The front is different cosmetically. The controls behind the panel should be the same. You might take a look at the control the **** is attached to. It is probably loose, not broken. I've had this happen, basically there is a thin nut that holds the control to the panel (**** removed).

 

I had the same thing happen to me and all I did was tighten the nut.

 

awesome. i will try that tomorrow.
