Be sure and check the drains under the hood, near the hinges. These areas quickly fill with water when clogged. Water should easily run off the windshield and out the drains.

If clogged don't use something that can scratch the paint which will cause long-term rust problems, instead use something soft like a chopstick or plastic stick.

There should not be any leaves/debris in these areas. Use a shop Vac with a narrow attachment to completely clean the area. If clogged it can take some time to get all the accumulated leaves and crap out. The drains are more easily found and cleaned when lifting the engine hood fully vertical.

If your car has an exposed rubber gasket, especially on the rear window, lift and edge and see if it snaps back. If it falls slowly the gasket is bad or is almost ready to be replaced.

In the trunks of these cars, down in the left and right sides, under the plastic inner liner are flaps for air to move out of the car. These flaps are often torn, or simply rotten. Water can collect in the sides of the trunk and will allow water to collect and condense upwards and into the trunk and then on the rear window.

The gaskets around the trunks are vertical for a reason: They channel water around and down.

If you are wondering whether your trunk gasket is sealing properly, use the dollar bill test: Take a bill and close the trunk on it. If the bill slides easily out your trunk needs to bee adjusted either at the latch and/or the hinge. It is rare that the hinge needs to be adjusted. (BTW, is is a great way to test a refrigerator door gasket).

The sunroof has drains in the corners. Do a search on this site using the words: sunroof drain
