Review: Dorman Quality - Ford Complexity! - 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).
Review: Very pleased - I needed to replace the left driver door switch on my 2004 Ford Ranger XLT and this was exactly the part I needed. Works great. Very pleased.
