When the trunk lid weatherstrip (seal) is worn, the lid may rattle, water may leak into the trunk, or dust may get into the trunk. After installing a new trunk lid (deck lid) weatherstrip, be sure to adjust the trunk slam bumpers so the power trunk latch opens the trunk on the first attempt.

a fine car for around town & short trips. It rides a little rough with more than 2 passengers and you can really feel the drop in performance.

This was my first car. Very good car until the head gasket decides to blow on you. I think after 1999 they did some improvments to the Neon but from 1995 to 1999, BEWARE!!!! These cars are in the junk yard for a reason. I really liked this car but the Head Gasket the big issue. Other than that This car is perfect.

The brake light wiring system/switch in my car needs to be replaced in order to get the brake lights and back flashers working again. I cannot find an online diagram for this system overhaul. Please help.
