Water in the footwell can be plugged up condensate drains.

The climate control modules do go bad and are pricey. Used X5 Versions sell for $250-$350 on fleabay. If you have any of the better BMW diagnostic software, you can try to connect to the climate control and see if you can read the sensors or actuate things.

I believe the power connector is separate from the multi pin signal connectors. Look for the large black 3 pin connector.


What? You don't have the guts of one on your workbench?
