I have a 97 150, and the door ajar light will not go off. I had to pull the fuse for the dome lights to keep from running the battery down. Anybody got any idea how to fix this? Just by reading through the posts it seems like the 97's have a lot of electrical problems. Any help would be greatly appreciated.

take some wd40 and spray quite a bit of it in the door latches. it wont hurt anything. what sometimes happens is the grease gue and gunk will build up and the latch wont close properly and the truck will not read the closed door.

 

That fixes it every time... it's a cheap switch that sticks... spray the hell out of it

 

been lqqkn all over for that switch thanks for the pix thats to easy

 

Theres A Sensor Plugged In To The Door Latch Inside The Door.. Maybe Goin Bad... My 99 Has The Same Problem I Just Dont Have Time To Mess With It Right Now... Have The Part For My Truck To Replace It Just Too Busy Working 2 Jobs And Runnin A Ebay Business On The Side The Part (latch ) Is Bout $145 Bucks From Ford Sensor Itself Is $13.00 But If You Buy Buy The Latch It Comes With A Sensor.. Which Ever Way You Want To Go,, But Remember Opened Packages Wont Be Able Take It Back..

 

This forum is how I fixed this exact problem. The wd-40 work great so does pb blaster

 

99% of the time its dirty and the WD40 will fix it so you wont need to replace the sensor/switch.
