Can my electric door locks be fixed (lubricated) without taking the doors apart?

Not a problem!.. Use straw in can of WD-40 and spray the hell out of the lock componets as best you can!! .. Best to do this with window UP using a butter knife to open a small gap at rubber weather strip at window then spray toward lock componets...do this on both sides of window..

i had the same problem on my f150.seems to be common on the f150,f250,expy,excursion,navigators,etc.mine got to where they would not work at all.it takes a little time,but not a bad job.it kept me from buying new door lock actuators,and now they work like they are on steroids,and this was 3 years ago!once you take the little motor out of the actuator,there is a little metal piece in there that looses resistance.all i did was clean it up,put a little piece of tin foil on the little metal piece,put it back together.been working very good for 3 years.the wd-40 may very well work,but i didn't try it.but i would have,instead i did find this info.copy and paste link. http://www.fordf150.net/articles/idx.php/0/018/article/How-To-Fix-Failing-and-Sluggish-Power-Door-Locks.html http://www.ford-trucks.com/user_gallery/displayalbum.php?&albumid=12198.......<<<<<<<this link is for excursion.
