"Door Ajar" Alert After Heavy Rain

[arcwcb]

So, we had a LOT of rain here in SE Texas last night. After driving the hummer in it, the instrument cluster displayed "doors" and sometimes leaves the dome light on. I did some searching and tried checking each door switch to see if one lost sufficient pressure, but none turned it off. This is the second time this has happened and it only occurs after very heavy rain. Any ideas what to check next? I'm thinking about replacing all of the door switches anyways, just to be safe, since they're so cheap, but I don't think that will solve the issue. Any other ideas on what I should check? Thanks!

Switches. Wiring harness in side door.

The door switches didn't change anything, I checked each door and manually actuated them. I spent a lot of time on the rear door since everybody seemed to have problems with it. When you say wiring harness in side door, what are you referring to?
