I've got a problem.

1. The temp display and time went blank. No problem. Didn't need it. Thought the pixels were just dead.

2. They just came back on by themselves a day or two ago.

3. Driving west now…long days. Cold this mrng. Turned on the rear window, defroster. It would NOT turn off.

4. AND the heater (rotatry dial) would not turn off. And the light for the heater and a/c would not go on. And the a/c would not work.

5. Seems the control panel is all nuts and dysfunctional.

ANY IDEAS OR SUGGESTIONS OR CLUES OR HINTS

Heat is constantly ON and rear defroster is constantly on and a/c won't go on. help….help….help

Sad

Rear defroster; might be the switch is sticking. Try cleaning around edges with murphy's oil soap, or the like, using an old toothbrush. Push into edge, let soak a few minutes, then try switch.

Rotary dial; valve for heater may be stuck, if so, might have to replace..sorry! Try turning dial with ac and recirc switches off?
You can pop off dial by pulling straight back, and check that where dial connects to control rod (on the back of the dial) hasn't rounded out.

good luck! tncean

The Climate Control Unit went bad. BMW no longer supports this part. ProgRama of Boca Raton remanufactures unsupported parts. Offers
3 year warranty for very little cost. Their site is http://programainc.com/

Since bmw doesn't offer parts to us anymore…this is a good place to shop.
