rain issues
Recently when it would rain for long periods of time, I would start the C5 and all warning lights and gauges would come on. If I would restart the car all would be normal. Today all warning lights came on, and stayed on no matter how many times I would restart the car. Dash gauges read either maxed out or not reading anything. Door control panels would not work, no power windows along with the AC would not work. I am assuming a ground issue of sort, any help would be greatly appreciated. Thanks in advance.

Look in the passengers foot well and inspect the BCM for water damage / dampness.
Feel the jute underlayment under the carpet (especially under the seat) and see if its damp or wet.

Ask me how I know.
Disconnect the negative battery terminal, remove the BCM and dry it over a mild heat. I put mine in the furnace room along with the carpet. They dry nicely there where its warm.Heres the tube behind the battery you need to FLUSH out with a hose:
Then there are the three udders on the drivers side:
The HVAC drain is on the passengers side fire wall:
