e46 climate control no display – BMW

The climate control display on my e46 BMW doesn’t work

This is a very common problem on BMWs, especially the 3-series. BMW control unitStart your diagnostics by smacking the instrument panel–hard. If the display lights up, that’ll prove that it’s getting power. But really, start psyching yourself up for a rebuilt control unit, because that is where this story will end. You will have to remove the unit and send it in to be rebuilt. Costs range from $50-$200. A new control unit from BMW is over $400.

Here are other common problems with the BMW control unit:
Is it switching itself off and on?
The unit resets itself
The control appears to be off but your heater or A/C still runs.
The control unit display is dim.
