If you pull off the heater temp. adjustment knob (yes it just comes off with a little tug) you'll see the control's hold-down nut underneath. My '05 only has 13k miles (bought it used in November) and that nut was very loose on mine. I could tighten it with my fingers -- just to give an idea about how loose it was even with low miles on the vehicle...

Once you get the unit repaired and the nut tigthened -- be sure to either check the nut 1x per year to make sure it stays tight OR do one of these things:

- Take the nut off, slip a locking washer onto the shaft and re-tighten it.

- Get some blue locktite (ace hardware of similiar) and apply to the nut/shaft. This glue's the nut into place and keeps it from working loose.
