stopped by the service dept at lunch. They had my AV under a PVC spaghetti rack, spraying the truck from all kinds of angles.
The entire interior was stripped down to bare metal .. except for the dash. Seats, trim, carpet, padding, everything.
Good news is that the leak IS NOT from the midgate back.....
Bad news is that is may be coming from the corner up by the passenger front fender/windshield. He said he needs to test more ...
FYI - apparently there is a small cavity down by your feet at the lower edge of the door frame about the size of a orange or grapefruit... It can hold about 2 cups of water before it spills out a small hole in the door frame into the passenger compartment! If you have a leak up front it will leak into this compartment ... but unless it fills up you will never know it. This accounts for us just now finding out we have a leak... This weekend was the first time we had parked the AV outside in a downpour. Compartment filled up and over flowed ....
He is still checking for more leaks ... whats to make sure that there are no more so he doesn't have to remove the interior again!
