On my crew cab I'm having door locking issues on the pass. rear door and now the drivers door. The pass rear door will not lock or unlock on its own but I do hear the lock motor working. On the drivers door it starting to not lock but will go down halfway but the door will remain unlocked after shut, but will unlock without an issue. Any ideas?

 

I did the foil wrap fix 4 or so years ago, and they still work great. Some have found lock actuators relatively inexpensively, and surely they'll chime in. Here's a link to the thread: https://www.ford-trucks.com/forums/9...-pictures.html

 

That was my thought on the actuators.
Thanks for the link but unfortunately the pics are not there anymore.

Edit: Just watched a video at the end of your thread and looks like I may be doing this soon. Thanks.

 

They're like $25 ea. on Rock Auto.

IMO, its just easier and quicker to replace the part. The Foil deal requires dismantling the lock actuator and re assembling. I did the foil on a friends Truck. Too much time and effort when you can just replace the entire unit in about 30 minutes and not have to go back in.

People were originally doing the foil deal when they were $60+ ea. from the Dealer.

 

I did the foil on mine as well. Now I have two motors acting up in the cold. Kick myself for not changing them out when I was in there....

 

When I replaced mine, I ordered them on Advance Auto's website (with a discount code, of course) for in-store pickup. They ended up at about 33 bucks each for BWD brand.

 

Scott save a bunch of time and just order a set of 4 12 universal door lock actuators ebay.
Use 12 test light on harness so you wire them up the right way.

Safe bet is to just cut the harness and BUTT connect the wires instead of the pinch connectors.

I had to drill 1 small hole on each door for the 2nd mount. Tons faster than the foil I did a few yrs ago.

 

I will try to post more info at the end of the day. If I remember.

 

I bought the cheap ones, put 'em in, then did the tin foil fix on the originals to keep as spares (figuring the chinese ones would fail sooner than later). A year into it, they're still going...

 

Ok I found this lengthy video about the tinfoil trick. I did this and it took me about 4 hrs total over 3 days. Its not fun. Between the fingernail pain and the cuts on me fingers. LOL


The fix worked out for me until a mechanic must of leaned on the driver's side and fried them all.

 

Here ya go Scott. I bought 2 sets and have 4 spares for under $50
Biggest thing is making sure the polarity is right so they move the right way. LOL

 

Here are Dorman's for $25 a pair.

Wrapping the thermistor with aluminum foil works pretty good, but you can cut a piece of copper to replace the thermistor for about a penny each (wink) much easier I believe

 

When i got my truck the locks weren't working. Found after market clamp on actuators in all 4 doors. Pulled them out, did the foil wrap to the factory actuators and wired them back in. Had to redo one about a year later but that was my fault, tore the foil putting it back in and it got weak. Still going strong 3.5 years later. Would do the penny trick if I had it to do over.

 

just get a set of universal actuators and add them in series with the existing ones. a set of 4 can be had for ~$20 and it does not take much to install them- or replace them if you need to.

did this on old green almost 10 years ago and the locks are still incredibly strong.
