Lately I've been having a water issue with my 2010 WK. When driving it after a hard rain, water pours out from the bottom of the Homelink buttons and from the A-pillar grab handle on the driver side. I know there is a TSB out for this exact problem. However, I'm now getting water up on the headliner as well as around the sun visor bracket on the driver side (see pictures).
It may be important to mention that this issue never happened until the Jeep started to sit when my dad became ill (was his daily driver).
I've also read that late model WKs did not come with the top windshield weatherstrip (see pictures). One picture is of my cousin's 07 or 08 WK with the weatherstrip and the other picture is of my WK without the strip. I'm going to assume that without the strip it would be easier for debris to build up and possibly eat away at the body sealer between the windshield and header panel. Hence, a probable cause of the water issue. I don't believe it's the sunroof drains since they run down the A-pillar and the placement of the water stain on the headliner seems to be farther back. But who knows.
I should probably start by pulling down the overhead console and A-pillar to see where exactly the water is coming from. However, as I don't want to pull apart the interior just yet, I may get some silicone sealer and apply it to the top of the windshield to see if that solves the problem. Perhaps when the Jeep was sitting a good amount of debris build up caused the sealer on the top of the windshield to crack and now let water in.
If anyone has had this issue, please share your thoughts and what you did to fix it.
