Re: door ajar light stays on after closing all doors
This is a common problem with Ford Explorer.
You all have the problem with the door pin switch. I had this problem with my 2003 Explorer before I trade in with another car. There were many problems after another.
Ford seems to have many problems with its door pin switches design. I had 3 of them fail after the third year.
To figure out the problem on which door, you need to check the pin switch right on the mechanical lock inside the door panel. Ford builds the pin switch on the mechanical lock. Use an ohm meter to check the 2 pins of the pin switch. Watch on the meter if you see it change when you push the pin switch in and out. If the meter does nothing with the pin in and out, you have that switch is bad. Repeat with other door until you find another bad one if you need to.
To access a pin switch, you need to remove the door panel and peel the door waterproof sheet. Then you need to remove the cable, electrical cable plug, and the latch that hook to the mechanical lock and remove the screws those hold the lock. The pin switch is mounted on the lock. It's easy to be removed. To put it back, you will have to reverse the other way.
Any question, come back to ask me.
