Door lock issues

Asked by Dannyj315 Dec 19, 2016 at 08:43 PM about the 2016 Ford F-150 Lariat SuperCrew 4WD

Question type: Maintenance & Repair

So today I noticed that my rear passenger door (
drivers side ) would not unlock or lock.  All the other
doors unlock and lock with no issues i.e. Using key
fob, manually or the lock and unlock button on the
driver side door. I'm assuming it's an electrical
issue. Wondering if anyone else has this issue and
how to fix ?

If you don't hear the actuator, it's either dead or the wiring harness came loose. If you hear the actuator, but the door isn't locking/unlocking, one of the locking rods came off. You'll have to remove the door panel to know for sure. Usually it's a bad actuator, they're straight-forward to replace, but getting your hand into the tight confines can be tricky.

Our doors lock unexpected, differences doors, different times. Dealership said cause was dirt getting in the door wells. We live on a ranch and it's real dusty. For this reason won't be buying another Ford.

GURUXRK2T I am having almost exact same problem as you. I have a 2015. First only drivers door would open . Then this evening the driver and passenger door work. Both rear doors nothing . I have never had this issue in previous winters . I could see the end of your post about what the issue is?

GuruBDFNL my dealer said it's a recall item, something to do with shielding, parts are on back order. Sorry, I can't offer anymore than that.

Strangely enough the next afternoon the passenger one started working then the day after one of the rear doors then hours later the other. No idea the reason. I was reading am earlier post that said ford told them it was do to the cold. Well I live in northern Canada and have never had this problem in th past and it's not even that cold here yet. I am definitely getting a hold of ford for it. Also for the first time ever my windshield washer sprayers won't work reservoir is full you can here pump running but no fluid coming out. I already checked that the tips weren't frozen and I use -45 degrees Celcius fluid.

So I found I had the same problem in my 2013 on the rear driver side door. The wire had broken. Since there was not enough wire to use a splice, I stripped a small section on each side of the wire and soldered them together. Then I wrapped with electrical tape. The connection is solid and the door lock works again.

In the wiring bundle from the door frame to the door. I'll post another picture of the wiring next.

I have the exact wiring issue and I went through 3 years of ignoring it before trying a new actuator just to find it was a broken wire and could be patched easily. Thank you guys!

2017 f350 XLT has power door locks, but when unlocked and I try to open the drivers door, I can see the “manual” lock/unlock rod sticking through the top of the door panel Drops into the locked position. This will happen as the door is starting to open, and sometimes when you close the door harshly. It’s as if the spring that should hold the manual pull rod in place ( unlocked position) has broken or is missing?

2013 F-150 The wire broke on my rear passenger door also. I soldered it back and it lasted about a year. It just stopped again yesterday. I'll crack it open this weekend and do it again. There's just too much bending in that joint.

2013 F-150 Eco Boost with Suicide doors. Pushing the lock/unlock button passenger door lock stuck down and had to be opened manually from inside handle. Once opened worked like a charm until a few days later did the same thing. Driver side door started same thing. Got locked out with keys in hand and neither doors would unlock. Key in door didn't work either nor did the touchpad. Had to get a Slim Jim to open the passenger door and that was even hard to pull up like it was binding or something. Its 89 degrees here so cold has nothing to do with it. Once open though the keyless entry buttons, the key pad and the key in the door work great! So it's not every time. Just when it wants to. Any answers to that problem?

New question, I replaced both the actuator and then the wiring harness. Now the actuator buzzes in the door when ever you open any door and my retractable step will not retract. The door does not lock or unlock? I would appreciate any help on this issue.

Iv had this same problem on two ford trucks. I lock the doors and come back and one won’t unlock, but later it unlocks. When it does this though you can take a pair of pliers and manually pull the latch up but not with your fingers. This leads me believe it’s not electrical. Dealership was no help either. Any advice would be appreciated.

I thought the lock actuator was broken and changed it but after wards I found that it was a broken wire. it is broken at the plug and I need to find a way to fix it or replace just the plug. Auto zone only has the whole wire harness and its quit a bit.

I had the same issue in a 2010 F150...pulled door panel, plugged in new actuator but that didn’t work. Followed all of your leads and checked the wiring between the door and the frame and sure enough...2 broken wires and 3 almost broken! Soldered 2 pigtails to the broken wires then little bit of solder on the almost broken wires and everything worked. Other broken wire was to the speaker which I did t even realize wasn’t working. Had to peel the wire casing back about an inch to find the broken wires as they were not at first easily seen...at first glance all wires looked fine, but when I peeled the casing back is when I found them all.

Had the same problem with my 2011 F150, found a couple of broken wires, used aviation type splice, rewrapped harness , works, great. Rubber boot was a little tricky to reinstall.

Sounds like mine is probably the wire, my problem is the door is locked shut, any ideas on how to get it unlocked so I can get into the door panel.

I have a 2017 F150 drivers side rear door won't lock or lock unless done manually.. thanks for the heads up to what the issues maybe. Calling the dealership tomorrow.

I got the same issue with my 2016 Ford F150. I've had it in for repair 4 times so far but every year since I've owned the truck the doors won't unlock as soon as the weather starts to turn cold. It's happening again right now but Ford won't cover the repair because the truck is off warranty. If it was properly fixed when it was taken back to the dealer 4 times, I wouldn't be having this same problem. The service sucks!
