Unique Electrical problem on 2006 M35

[bidyut]

I have 2006 M35 and it has 100K miles now. Recently during this cold weather, a weird electrical problem is happening. When I start the car in the morning, the center console including audio system, navigation and the climate control keeps on going on and off until the car is heated a little and then everything works fine. I have searched google and didn't find any such problem faced by any other owner. So if any of you have faced such problem, can you please help me finding out the issue. Before splurging money for the repair, I want to see if there is something that I can fix it myself. I have a feeling that there is some contact that is getting way too cold in the night resulting in such issue.

Thanks for the help.

Hey there. First time signup longtime member of nicoclub. This sounds like a TSB that indicates a slow leak near the bottom right corner of the windshield. Water gets into the BCM and causes similar issues. It could also simply be minor contact corrosion. You can fix this by disconnecting all connections and reconnecting. Good luck.
