Door wire harness shorting out due to water/moisture.

I have a 2011 JK and found out that the driver side door harness connector has water/moisture buildup inside, causing short and erratic dome light flickering while door is opening. I'm suppose to get the corroded harness replace by the dealer next week (part backordered). It has been raining here and I was trying to track down where the water could be entering, but no luck! I couldn't find or see any water track marks under/near the connector. Has anyone experienced this? The dealer couldn't explain to me how the water got in there! I'm afraid that this problem will re-occur even after the harness connector has been replace. Should I ask for a leak test?

Pics of the problem would really help.

There are a lot of reasons why moisture got in there. What does the other side look like?

I would do my own leak test before I took it back to the dealer to have the harness replaced. That way you are knowledgeable of where the water might be coming from.

Try this:

Definitely ask your dealer to find and remedy the source of the moisture intrusion.

A proper application of dielectric grease may also be in order. Ask your dealer.

Good Luck!

Thank's for the reply! Here's the pic of the female connector. I partially disassembled it, as you can see the light blue silicon boot where moisture can be found. So I added some dielectric grease on the boot and the metal pins. And no moisture can be found on the passenger side connector.

That's good news about the passenger side. Now, on to finding / fixing the water source...
