My wife's minivan had the same exact same problem....especially on a bumpy gravel road....on off on off on off...AHHHHHHHHHHHH!! (this was both the beeps and the I said AHAHHHHH!)

I resolved it by figuring out which door was causing the issue....very irritating the flashing interior lights, etc.......the issue is likely that the rubber gasket is worth enough to not push the sensor in completely....

  • locate the sensor on each door....little 1" shaft like area in the door pillar area...pressed in when the door is closed
  • with the engine running, open each door (one at a time) to manually press this switch in ( to identify which door is causing this irritating issue)
  • once the troubled door is located...look to see where it would make contact on the door itself
  • look for a rubber nickel sized plug on the door
  • it is likely worn slightly, or pressed out of shape
  • to resolve my wife's issue, I turned this plug a 1/4 turn or the 'unworn' area
  • this worked really well...although it took a few 1/4 turns to figure out the best fix
  • ultimately it was an irritating fix....but the problem is/was much worse than pulling over every now and a again to 'fix' it...esp. at night (think flashing interior light, beeping..esp. when the kids had just fallen asleep!!!!)
  • was a little fiddle process, but once you do it once then, you can fiddle some more
  • long-term, perhaps get another 'plug', but my solution worked really well

When I start my 1998 Chevrolet Cavalier the dome light goes on & will not shut off while the car is on, when you stop & shut the motor off it goes off after about 5 minutes. Any ideas on how to...

Sounds like your door switch is acting up, in most cases it is the drivers door that is doing it, do you have a light on the dash that says the door is open, some cars have it and some don't. i have seen the switches wear out after alot of use.

The dome lights and floor lights stay on in my 1993 Buick Regal Custom. I have made sure that all doors are shut tight and still they stay on!!

This sounds like one of your door jamb switches have stopped working.

This could also be the dimmer switch on the dash. If it has failed, it could keep the lights on.

Also make sure you don't have the dimmer switch turned all the way up to where it keeps the lights on all the time.

2008 chevy express dome lights won't come on when doors are open but will come on with the switch on the dash

Dome light issues with Chevrolet Express van. Easy Fix
To the right of the headlight switch/knob, there is a square plastic base for the "dimmer" It has a post-like button in the center .. above the post is a switch - it doesn't look like one (it reads "Dome Off"). Press it in, and the interrior lights will come on when the doors open, etc. I just had my van serviced, and had to do this myself.

2001 Ford Escape, dome light will not go off when door shut, but door ajar light is dark?Could this be the door switch? are there different switches for the door ajar light and the dome light? How can I...

The door switch provides a ground to the dome light... so there is no danger to you if you want to attempt a removal of the switch. A rusted or shorted wire in the door switch (of any door) will keep the dome light on.

Door ajar dash trouble and dome light stays on even if all doors

The door sensors will need to be replaced. A screws can be removed and then a wire can be taken of and you then can replace the switch.

Dome lights won't turn off

Been having a problem with the dome lights on a 99 chevy blazer. Still can't figure out what the problem is. There is a dome light overide button located under the dimmer wheel. When I push the overide button in the dome light goes off, but when I open any of the doors the dome light will not come on. When the overide button is out the dome light stays on all the time and will not turn off even though every door is closed. I checked all the pushbuttons and everything tests good. Has anyone had this problem and know how to fix it?

Dash lights and rear lights go out if driver side door is opened

There is a electric contact in the door to turn on the dome light when open and off when closed. It sounds like that switch is bad or the wire attached to it has fallen off behind the doorsill. It may be another door though, since all work the dome light. Try opening the other doors one by one to see if they light up the dome. Theres no guarantee because the seat or seatbelt may come into effect.

Overhead lights

check you dimmer switch. the dimmer switch is what controlles the interior dash lights and dome lights. you might have acidently hit the switch and it may have pushed it up from the position it was at. if you push the switch all they up than you interior light will come one even if you shut the car off and pull the key. turn the dimmer switch all the way down and see if it still does it. if not than wait until it gets dark and go outside and turn the swich up until ou can see the dash lights. but remember if you turn it up to far the interior lights will come on.
