Hey guys, new AZ guy here. I just purchased an 02 F-250 Super Duty 7.3 diesel. I have this problem with the door ajar light and dome light, only WD 40, brake cleaner and PB blaster have all proven in-effective. I tried leaving all 4 doors on until the dome light timed out. When I close the front doors after the dome light times out, it comes back on?? The backs do nothing. Which ones are screwed up??? How should I proceed?

 

Great tip thanks bo

Wow, i can't believe i didn't find this post b4. I have had this issue for 3 yrs now. I've noticed mine is perfect when its cold out, but when it gets over 65 degrees this thing wont shut up. I'm gonna try this first thing in the a.m. and hopefully it will work.

 

I cannot believe that this simple shot of wd-40 has made my life miserable for the last 3 yrs! Thanks alot man. I'm so happy it worked!

 

how didi you fix it ??

 

It worked for me today!!!!!!I tried fixing it and got mad.I looked it up on here and thats all she wrote.Should have looked here first.THANKS

 

Thanks, I have had this problem for at least the last two years. Sometimes the lights would go off right away or take about 20 seconds. Other times the lights would stay on for hours. I only had this problem with the passanger side door. I tried the WD-40 trick and it worked right away. Thanks again, I was ready to go out and buy a Toyota pick-up to replace my 1998 F-150.I think the WD-40 cost me about $2.00 compared to $30,000+ for a new truck.

 

A buddy of mine had the same problem who lives in Oregon and his buddy is the service mgr at a dealership, replaced the "light relay" thats part of the fuse panel and voila no more dinging, lights or anything! Did this in December, and nothing still.

 

2002 f-150 is doing the same thing but my cab light is on as well, will this fix that problem to?

 

Been having a similar problem the last few days. Was going to pull the interior light relay to prevent battery discharge, but couldn't find the stupid interior fuse panel. Down and to the left of the steering column. Nonsense. Saw the advice about WD-40 on the latch side instead of the hinge side. Looks to be improved. Will apprise of success. Ghost of Sparta, out.

 

I have a 2008 f150 and the dome light is stuck on along with the lights outside on top of the rear window. Your WD40 fix makes sense except I don't see any place to spray, my doors are totally different from the picture you show. they are covered in the same material as the dash and none of the things I push on move. I opened and reclosed all the 4 doors a few times and lights still stay on. My wife has to use it to go to work and unhooking the battery and tightening it back up would mean she would have to take a step ladder to reach it. Our dealership is closed now on weekends so she would have to take off work to have them look at it. We are both in our 60's and I don't get around very well anymore. Any ideas or help would be apreciated. Thank you

 

the air bag warning lamp in your dash is blown

 

hi there new guy here. My wife's 03 Explorer seems to be having this problem. Door ajar light staying on as well as the dome light. Also finding the door lock button is not responding on the driver side. I can roll the dimmer switch off and turn it back on and the door ajar light and the dome light turns off, but as soon as i open any of the doors the problem comes back. Any suggestions? I've been spraying WD-40 in all the door latches but doesn't seem to be working.

 

Worked!!! Thank you!!
