My locks on the driver’s door do not work when the vehicle is parked. The locks work find from the other doors, the keypad and the remote. Also door ajar light comes on. When the vehicle is moving the locks work fine.
I replace the lock switch, but it didn’t make any difference .I lossen the three screws holding the mechanish sprayed with lots to WD40 and moved the mechanism aroubnf a little, it worked a couple of timews, but then back to nothing.
Thinking about replacing the door ajar switch, but not sure of the relationship to the lock. Any thoughts are appreciated.
Welcome to the forum! There are several threads on this forum pertaining to the door ajar switch in the latch getting dirty and needing to either be cleaned or replaced. Additionally, there are several threads related to broken wires in the accordion boot between the door and cabin. The power door lock switch being intermittent is probably due to the broken wire issue. The door ajar indication could be a broken wire or it could be the switch issue.
I had similar electrical issues with my 02 xlt. The dome lights would stay on until the battery saver feature turned them off, the accessory delay wasn't working, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, the delayed accessories didn't work, etc. The alarm would beep twice when I armed it. Recently all 4 windows stopped working. Most recently the driver door lock actuator stopped working.
A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 3 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ. I had to repair the pink/black wire to fix the driver door lock actuator.
Be sure to take your time when looking for broken/damaged wire(s). Check all the wires for breaks/damage. When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.
On a side note, before going through a complete replacement of the switch, you can spray WD40 into the door latch opening on each door, as these become stuck sometimes....and this can alleviate the issue.
This worked for me, after going for more than a year of the "door ajar" light coming on occasionally...mainly after a car wash, high humidity, or rain....making me unable to lock/arm the vehicle from the door keypad and keeping the dome lights on. Worth a try....it worked for me :thumbsup:
