Driver side door ajar light comes on 2006 chryler 300 c

Check rubber bung in door makes contact with door shut sensor on car body. May need to replace the rubber bung in door.

Can you tape a coin or two onto the door at the spot that hits the light switch? If not, just remove the bulbs.

The latch striker post needs to be adjusted. check for broken plastic roller on the post.

same thing happened to me. also interior light stayed on and power locks wouldnt work. It was our door latch assembly in drivers side door. part is $110 - $250 depending on where u get it

first I would be looking at the body switches for dirt or rust causing a false signal.. then I would adjust the part of the alarm that the wind affects..it should be adjustable for sensitivity..the dealer service should be able to advise you..if not check with an alarm service company..that installs these systems..good luck..

Found that fuse for interior lamps. It's located in the smart junction box.

Check door switch connection and operation.
If the door switch is part of the door lock mechanism, within the door itself, then remove door panel, disconnect the mechanism's electrical connector and re-check that the interior light no longer comes on with that door ajar. If it doesn't, then you likely have a faulty door lock mechanism, which you will have to replace.
This faulty switch will also have the affect on your random central locking function.


This is not likely connected to the engine performance issue.

It's in the driver door most likely do you have keyless entry and do you use your key to punch in the #s if so the seal is broken and letting water in if not the driver door module deals with all and also the door wire that's at the latch lock where you close the door that wire could be breaking making the interior and door ajar light comes on but all problems are in the driver door your master lock control keyless entry and alarm and door ajar all go through the driver door module check for moisture in it or corroded connections and broken wires also have fuses checked for blown ones have fun in your techno boogie box and if you do use your key press the key pad buttons get out of the habit

Sounds like a bad door switch on one of the four doors. The switches have multiple contacts to serve both the dome light and the alarm system. The actual switch button is under a rubber boot with ribbed sides. The switches themselves are under the interior trim behind the doors.

there is a switch in each door that senses the door is open, it is called the door ajar/courtesy light switch (imagine that), they stick and have this problem, replace it.
