What I can't fathom, why aren't these light assemblies water tight? It seems like the last water tight light assemblies we had were the old fashion seal beam headlights? Water intrusion seems to be a constant for about the last 40+ years now, across all makes? Long ago I recall drilling some 1/8" drain holes in parking light assemblies so they wouldn't fill up with water.
Lot's of hand wringing and teeth gnashing on the Durango forums about the race track light fixtures filling up with water and shorting out the LED's. So far, we've been lucky with ours.
They should've been. It became a known defect for which Ford did not step up to handle for customers.
Buick had the same issue on the backup lamp (a huge giant 1 piece lamp) on the Rendezvous. The backup lamp would fill with water. Ford had a similar issue with the applique on the lift gates of Explorers and Mountaineers where water would leak through the lower gasket for the back glass, settle behind the applique, and when the water would freeze and expand, it would split the applique in half vertically. We used to get customers reporting claims for this one, but it's not a covered loss. Several cars have issues with headlights fogging up, while it's never a problem on other cars.
