E39 Air Cond Instrument Panel
What a bad day. Notice that the button used to increase air-cond temperature on the passenger's side has cracked. Tried to peel out to super glue it. Unfortunately the red triangle fell into the instrument panel. So decided to DIY. Took out the panel (with the LED display). Pried open the back cover to the instrument panel but found it hard to re-attach the cover back while ensuring all the tiny springs (which give the buttons their bouncy feel) are still in place. So send the thing to the dealer. They managed to re-attach the cover back to the but now the problem start. I can't off the air cond by pressing the air volume to zero. As soon as it reaches zero, it will automatically start/switch on again on its own. Anyone encounter such weird electronic problem before. Please don't suggest for me to bring the thing back to the dealer to open again to fix the same.
