Dorman 901-351 Door Ajar Switch Compatible with Select Ford / Lincoln / Mercury Models

Dorman did their job! As usual, this Dorman product is excellent and a perfect replacement part at a much better price compared to OEM Ford parts.I gave just 3 Stars for Easy to Install since we are, in fact, dealing with a Ford. I typically find many jobs that 'could' have been simple, are over-engineered and therefore a bit trickery than they should be.That is precisely the case with this replacement.Getting to the part is easy. The door panel easily lifts straight up after removing the window/mirror switch armrest part and then removing two 7mm screws.Then the fun begins. I had to remove the three 27mm star screws at the rear edge of the door that hold the actual door latch in place on the door. Then I tried to manuever the door latch within the confines of the door cavity which was hampered by the door window track rail and some locking rods that attached to the latch. I removed the one rod that went to the manual lock knob.According to everything my research found, it should have been a simple counter-clockwise 1/2 turn to remove the old switch. But, regardless of how hard I tried it would not budge. THIS is when you worry about breaking OTHER parts that you weren't intending on replacing but now are faced with having to replace!Thankfully, I FINALLY got the old switch to move! I'd already unplugged it so it dropped free into my waiting hand.A little tab on the body of the switch was the only part that broke. No harm done, but what a pain.The new switch fit into place and locked into place pretty easily. Plug the connector into it, replace the threw 27mm star screws and I was ready to put the door back together.This job 'should' have taken me about 15 minutes, but ended up more like 30. Oh well.The switch works! I was replacing it because I did not like that the interior lights weren't coming on when you opened the driver's door. A safety issue for anyone driving the truck. In addition, that switch alerts you to the door not fully closed, and the key still in the ignition (Helps to prevent you from locking your keys in the vehicle).

Nice working

perfect fit, took care of the failed part

I installed on my 2007 f150 and the replacing the part is fairly difficult due to limited space and no visibility. The part fixed my door ajar issue at first but only lasted from early November thru mid December. The issue has since gotten much worse with the relentless dinging, dome lights coming on and off and the radio and light not shutting off when the truck is turned off. The part is already irritating to access and replace so do yourself a favor and buy the genuine part.

Direct replacement fit. It takes a bit of effort to replace, but easy enough for a shade tree mechanic.

Product as advertised

Didn’t work for me but maybe it will for you. I was sure it was the driver door sensor that was bad. It’s either a different door sensor that is bad or the sensor they sent was damaged when the driver tossed it over my locked gate into my yard where my dogs were barking at him right before they ripped the box to shreds. What kind of person throws a package to barking dogs? I found the sensor on the ground in my yard out of the packaging. Hard to use process of elimination for my issue at this point. It’s not the seller’s fault but the Amazon driver. When I ordered the sensor it said it would be delivered Monday. It came 3 days early on Friday. I wouldn’t have even known it was delivered if I hadn’t found this small piece of the Dorman box on the ground this morning. I’ve told them time and time again to leave my packages outside of my gate. Despite the delivery issue, the product fit perfectly on my 2005 F250 XLT 6.0

The switch is working good now for 3 months. I just dont like that it's cheap plastic. The one on the drivers side came from the same place but was very strong metal. I have it 5 stars because it was very easy to install and is still working good. For how long. I dont know. But it's working great for now
