Passenger side front headlight assembly full of condensation and water.

Another option: ... eBay... Got plenty of em!! Way WAY less than that price!!!!!! Check it out before you do anything else!!

I understand your frustration. Lots of things break and fail over 90,000 miles of driving. Everyone drives differently and in different conditions. A headlamp assembly is subject to lots of wear from the weather, stones and debris from the road. You do not have to purchase a new headlight assembly from the dealer. There are many non-General Motors options available. I would take the car to a body shop for an estimate with an aftermarket headlamp assembly.

AGREE WITH BOTH 1&2
