Common Issues with a Chevrolet Cavalier Door Contact Switch
A door contact switch will normally fly under your radar among all the parts that make up your Chevrolet Cavalier. The roles it plays in the functioning and security of your vehicle are far too important to ignore. One, the door contact switch allows you automatic, remote control over your locks-if you have it installed. Two, it determines the state of your door and informs you--via a warning light on the console--whether any door is still ajar. Three, it works with the alarm system and forms the "seal" that thieves break to trigger the loud, blaring alarm. There are a few things to watch out for to determine whether or not your door contact switch is starting to fall apart:
Door is always ajar
This warning light helps to inform you when one or more doors are, well, ajar. Sometimes, though, problems arise and no amount of slamming and securing of the door seem to get the light to step down. The first thing to check is the door contact switch located near the door lock. It's funny, but many times, the cause of this problem is a dirty door contact switch. If cleaning it-with a moist, clean cloth-does not solve the trouble, you should then check on the electrical components. You can do this yourself by accessing the wiring behind the door panel. Should any wires be frayed or damaged, a little electrical tape solves the trouble in a jiffy. It's better if you let a professional handle it if you have any doubt--you might take the system and a few others around it if you go wrong.
Slow remote response
Granted, the problem might lie with the battery in your door remote. If--after replacing the battery--the problem persists, you might start checking the motor behind the door panel. While you're at it, though, it's a good idea to include the door contact switch in the inspection as a fault in its wiring also contributes to the failure of the auto-lock. This is a much brighter prospect that the motor of the mechanism breaking down--because it's a cheaper replacement job.
