Tip & How-To about Ford Taurus
This is a common problem for these makes. They use a door ajar switch that is attached to the door
latch assembly. The most common one to fail is the driver front.
Something you can try is clean the out side of the door latch, the part that actually holds the door shut, with brake clean. Don't be afraid to liberally spray into the latch assembly. Let it dry and then liberally spray the same area with penetrating lube. Again don't be afraid to spray it in every nook and cranny you can get into. Then open and close the door several time. Spray it again with the penetrating lube and repeat a couple of times.
If the door ajar light goes out when the door is closed problem solved. If the light continues to stay on you have two options.
1. Your can remove all the door panels and unplug the door switches one at a time until the door ajar light goes out. Again the switch is located on the latch assembly and has a two wire connector. Once you find the one that is stuck you can remove it and either clean it/lube it until it starts to work again or replace it. The switches twist into position in the latch assembly and if it's your first one it may be easier for you to remove the latch from the door to understand how the switch is attached. Neither is an easy task your first time.
2. You can have a shop use a scan tool to communicate with the GEM module to see what switch is stuck open. You can then focus on that door. There will be a diagnostic charge for this. Call around and see what various shops in your area charge for this. They will know exactly what you are talking about when you explain the problem as it is very common.
Hope that helps!
