driver door ajar light on
My "Driver door ajar" light is on and stays on. The window will not tuck inside the seal and when I activate the alarm I get (2) two horn honks instead of (1) one. This started about 3 days ago but after opening and closing the door several times finally went off. But now it is on and no matter how many times I open and shut the door the light will not go off and the window will not seal. Any ideas anybody??

If you get 2 honks when locking then the system is reading a sensor as open. Makes sense, since you are also getting a driver door open alert - so that tells you what sensor is going out and should save some time in getting the replacement part.

I just fixed this on my '07 GT 6 months ago. There is a sensor in the door behind the latch that is failing. You have to replace that. I think I have part numbers saved still, along with instructions on how to do it. Can't check until tomorrow morning, but I'll post them up if I find them.

Ok, here are the instructions for replacing this door ajar switch.
Door panel - http://iihs.net/fsm/?dir=441&viewfil...im%20Panel.pdf
Door Latch - http://iihs.net/fsm/?dir=466&viewfile=Door%20Latch.pdf
Door Ajar Switch - http://iihs.net/fsm/?dir=466&viewfil...r%20Switch.pdf
The switch is attached to the latch, so you need to do them in this order.
I had a problem with ordering a generic switch online, when I plugged it in it worked exactly reverse of what it should. So make sure you get one that is specific to the mustang.
I'm afraid I can't find the info for where and what part number I purchased, but I'll keep looking.
Good luck.

I am having the exact same issue with my 2008 Mustang

I am having the same issue with my Mustang. Where did you find the sensor and would replacing it be the same as with ano older model?

I fixed the "driver door ajar" issue by replacing the door ajar switch. I first replaced the switch with a aftermarket part from an auto parts store and it was operating in the reverse as it should. When the door was open it thought it was closed and when the door was closed it thought it was open. So I replaced it with the OEM part from the dealer and it fixed the problem. The part number is Motorcraft: SW6121 Part Number: 4LZ 13713 AA. The part cost $48.16 with taxes from the dealer. Follow the instructions from "jayguy" posted on 11/18/13 and also they have good videos on how to remove your door panel on youtube. Let me know if you have any questions.

Do NOT try this at home!
Just kidding but ****!!!! It's a hellofa job. Make certain if you're doing the driver door, get the twice as expensive proper sensor...go figure🤬 $50+
getting the outside door latch rod off proved impossible for me. So I made due with dropping the mechanism down enough...
Be carefully to remember where you disconnected the sensor from, it is tricky.
Push and twist left to get er out. There's a video on YouTube where dude makes it look so simple on passenger door. Pops right out he says! Push and twist, easy peasy...right!🤬
Disconnect all wires from the interior panel and put it out of the way. I didn't and broke the connection to the lock switch 🤬
Have star type sockets / wrench keys on hand...
try your best not to force anything! I broke one latch side off the sensor putting it in the wrong place. But the one side held it tight. Phew...
Get ready to do some serious cussing.
