Chrysler Repair: Door lock noise and audio tone at every bump, door latch, striker plate


Question
RF - Thanks for any help!  About a week ago, whenever I hit a pothole - my door locks would "click", like they were locking again (like when getting up to speed for the first time after stating the car.) Also an alarm tone/beep.  Now it has worsened - happens on virtually any bump. If rough/grooved pavement, locks & tones are cycling almost constantly.  Door locks don't pop up, just sound like they're locking each time.  1999 Sebring LXI

Hi Axe,
There is on each door a pushbutton switch mounted in the door frame which senses when the door is either open or ajar slightly and when it senses that condition it signals the body computer to make that sound, and then when the door is sensed as being closed it will automatically lock the doors if the car is going faster than about 15mph. So probably what is happening is that although the door is latched in the closed position the latch is not actually tight enough to push that button switch in to point where it firmly stays in the "door closed" position. What you need to do is adjust the striker plate on the door frame that secures the door latch mechansim to a more in-board position so that the door is held more firmly against the door frame/gasket and thus keep the push button in the "closed" position.
The striker plate is usually held in place by 2 screws which if you loosen them will allow you to move the plate toward the inside of the car a bit more, then retighten the screws and verify that the door can still close to the fully latched position and be firmly in that position once you are in motion even on a bumpy road. The convertible body is more flexible so this sort of a problem is more common. If that doesn't help then you can build up the surface of the inside of the door skin where it pushes on the button by epoxying a penny to the door so that it will push the button in further and thus avoid the false ajar signal from being sent.
