Electric Door Locks Not Locking Properly

I am having intermittant problems with my electric door locks not locking or unlocking on my crew cab. When this happens, usually one lock works correctly and the others don't. I am assuming that there is a relay probably with dirty/worn contacts, and the lock solenoids are not getting enough voltage to acutate the locks. There is not a relay in the fuse/relay boxes that is designated as such.

Is there a relay underneath the dash somewhere? Is there anybody that has experienced this before that would know?

Thanks!

My bet is that the actuators are going. I've replaced 1 out of 4 in my '02.

I had a strange thing happen like this on my truck. I pressed the lock button to lock all of the doors as I was getting out of the truck. All of the doors locked but after about 3 seconds the drivers door would unlock before I could even get the door shut. It did this about three times and then I locked it using the key fob and everything went back to normal. Has not done it since.

Gremlins I guess.

I did a little search and failure of the acuators seems to be the common denominator. Just can't believe that 3 of the 4 would start failing at the same time!

Thanks!

All four of the actuators in my '99 crew cab failed about the same time. I bought a $29 aftermarket lock kit, wired it in, and now have four locks that operate briskly. I left the dead Ford actuators in the doors. The Ford dealer claimed it was an underdash actuator, but after 3 attempts (by the PO) never fixed it. IMO, it was the door actuators all along.

Took me about 45 minutes to replace the passenger side atuator. Here's a link to some gallery shots someone posted for doing the job. https://www.ford-trucks.com/user_gal...?userid=190355
