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.
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.
