Electrical issue

You are correct that this is water getting somewhere. More then likely it is a wiring harness in the door.

The way to find this, is to use a hose and strategically start watering down portions of the car. Don't just spray wildly like you would if you are washing the vehicle. Start soaking portions of the vehicle allowing the water to only run in areas that you want so that you can find the area that is causing the issue. Once you find the area, you can start disassembling it to find the problem area.

Does this make sense?

Hello,

Probably not, but you should reconnect it if you can see its original place. Your hearing the relay, Was there moisture in there?

Hi Christy,

Okay, has the car ever been in an accident? This issue just started clear out of the blue? Does the car have a sunroof? Water maybe getting all the way down under the carpet but the carpet may not feel wet. Feel around the floor for wetness. I have seen sunroof drains disconnect in the window pillar and the water got into wiring and other electronics by the kick panels, under the seat and carpet. Let me see if I can find info on what may be under window pillar and the carpet.

Hi,

Then I would check to make sure the sunroof is draining properly out the bottom. If you run a hose super slow or a cup of water so the water doesn't run down the front window and only goes into the sunroof drain you should see water come out under the side fender by the tire. If it doesn't come out there its running into the car. Some car have a drain on each corner. The rear ones will run down the rear window pillar and out the back by the tire under the fender. My suspicion is one or more of the sunroof drains are plugged or disconnected and water is getting under the carpet and moldings so you cant feel it wet on the surface. If you can pull up the carpet at the corners and get your finger under the floor pad and see if its wet. I have seen inches of water build up on the floors and the carpets feel dry
Let us know how they drain and if its wet under the carpet.
