If your "door ajar" or "dome light" is staying on, Read this.

Spray in both doors then open and close them a few times. sometimes you will need to spray a lot of WD40 and it will run out the bottom of the doors. Just leave them open until it drains out. thats exactly what brought me here to f-150.com back in janurary in the first place ...zap!

When you spray use the spray straw and point it well up into the lock area where you can't really see. That's all the dealer is going to do to get your $500!

I indicated earlier to spray with the spray straw. I used Fabulous Blaster by PB. It's a penetrating catalyst!

Its just not the F150's. My wifes 97 Taurus had the same issue wtith the domelight staying on from a sticking latch switch. WD 40 works everytime. Great thread!

I know this thread was all but dead, but Ihad this problem on my navi that had gotten so bad I was pulling the fuse to stop it. I then tried this (long before I knew about this site, damnit) and slammed the doors a few times and now it only happens intermittantly every few months and even then it usually goes away. The guy at ford told me the switch was magnetic and that they frequently had this problem. Slam the shiat out of it once you have sprayed it real good, and if that doesn't fix it, take it and get it fixed. Its an aggravating SOB

I'm glad to know I have a honest mechanic, if there is such a thing! lol I had the dome light problem about 8 months ago. So I took it in to the mechanic and he called me and told me it was fixed free of charge. He actually showed me this neat little trick too. I was impressed with his honesty!
Good thread it works every time!

Thank You!!!! Thank You!!!! Thank You!!!!

I just did this WD-40 trick last night on my 99 F-150 and it worked awsome!! This had been driving my nuts for 3 weeks that I pulled the 15A fuse, but I couldn't put the windows down b/c there on the same circut. I was so close to biting the bullet and droping my truck off at the local "stealership" to fix.

Anyway no need to pull the fuse to get the dome light to go off anymore

well my dads expedition is doing this too it probably is on all fords from around 97 and up

In light of similar probs in various Ford models,I'm surprised FOMOCO has not addressed this issue. X

To the people that tried this and it didn't work: Try using ether(starting fluid) instead of WD-40. WD-40 worked on my truck, but not on my uncles. We used ether and it fixed it.

I had the same issues with my 98 scab, tried the WD40 along with everything else I could get my hands on with no luck. Finally ended up replacing the $10 relay in the fuse box and have not had a problem since.

I used the wd-40 trick and low and behold the light went out. It was driving me nuts...

Now I notice that the light will stay on ocasionally until I turn the key to the on position then it goes out.

Any ideas?
