    Does it really bother you so much to fix it? If you pull on it, it should pop out and maybe there is some dirt in there?

    Sounds like the cable that runs from the knob to the underdash area to allow the coolant to run through is damaged or disconnected.


    I would start by taking it apart, remove the knobs and the back panel. There are 2-3 phillips head screws that hold the control mechanism on. Remove them as well which will allow you access to see if the controls are all still hooked up. My guess (without being there to know for sure) is that the cable is disconnected from behind the switch.

    G/L and let up know what you've found!

    My 99 does the same thing. The reason it clicks is because your cable is probably getting stuck or the lever at the heater is getting stuck. It doesn't bother me enough to look into it further. If mine clicks I just turn it back and slowly try and move it or just say F- it and leave it be for a little while. But it eventually moves again.

    Back to square one after the 2001. So...
    You might also want to check that your heater control valve isn't seized closed.

    Under the hood, it is up high against the firewall in the heater hose that passes through the firewall to the core inside the cab. You'll see the control cable and the little valve spliced into the hose. See if you can grab this an operate it freely. This might also give you a clue where the cable is stuck/hung up. If it is OK here, you will know the problem is likley inside/under the dash.
