So I am driving to work this AM in a pretty heavy rain storm and my door and dome lights come on as well as the idiot light showing one of my doors is open. Since I am the only one in the car, I open and close my door really quickly thinking I had my door open partially. Still doesn't do anything.

Then all of a sudden the light flickers on and off then fades away like a normal operation. This happened before I had a chance to pull off the hwy to check my to see if my other doors are closed or my rear gate.

Just a few minutes later it happens again but for a shorter duration and turned off again. WTF is that all about?? (dunno)

Any ideas?

I had my front wipers on slow and the rear on intermittent. Also had my front and rear defroster running at a med fan speed & my driver side heated seat on. I messed with all these electrical accessories with no change.

Shooting from the hip I thought somehow water or condensation contaminated the door contact switch on my driver side door. I haven't looked yet to see if its protected with a rubber boot but it was the only thing that made sense (water gets in and shorts out the switch making contact??).

Anyone else have this issue? Ideas????? Should I bring this up to the dealer??

My first guess would be the door ajar sensor is freaky.
Take it in definitely.
