I've searched a little but didn't find my answer. The rear lock on my son's '97 doesn't always unlock. When we hit any of the lock/unlock switches, the lock button will move up and down, but sometimes it doesn't move up enough to unlock the door. Does this sound lock a failing actuator or a lubrication problem in the linkage or lock mechanism? I am in inclined to start with a good lube job of all moving parts in the lock system to see if I free anything up. Ideas? TIA

Did you ever find a fix for this? I am having a similar problem with one of my rear doors sometimes it will lock and sometimes it will not, and the same problem with unlocking.

Use the search tools and scour the archives. VERY common problem and lots of good threads on how to fix.
 






Yeah I already did a search, and nothing addressed an INTERMITTENT problem. It is getting hard to try and remember to check if the rear door is locked or not.

Intermittent will become permanent. Very common on 2nd gens. I'm currently dealing with a loose actuator, a loose handle and have dealt with the latch issue in the past. I love my Ex, but the door design in them SUCKS. I thought the rear wiper was bad.

Just do whatever fix applies to you as if it is dead (and it will die).
 






Check the stability of the actuator, it should not move or be loose at all.
Often the "Rivet" that holds the actuator in place either falls out or gets pretty loose.

I hope this helps.

Nice red "X" :p:

Yeah, I was checking my Ford service DVD tonight and it mentions the rivet. I'm pretty sure mine is toast because the actuator is completely hanging there (but actuator still works). Probably happened this past weekend when I was playing in the mountains this past weekend with my son. The road was VERY washboarded. Lots of creaks I didn't have before and the actuator seems to be a casualty. :(

Any ideas on how to secure it without a rivet?
 


















Hi Celly;
I went to a hardware store and picked up a small bolt and nut.
I think it was a 10X32 about 5/8ths inch long.

I pulled out the actuator and placed the head of the bolt inside the actuator holding clip (There might be a piece of the old rivet remaining, just drive it out with something small and you will see the mounting hole on the retainer clip). You will need to pull the actuator out of the retaining clip and put the bolt in with the threads protruding out. I remember it was a real pain to get the 10X32 to stay in there. When I think of it now I would have placed a piece of tape over the head of the bolt head to hold it in place. Getting the actuator back on the retaining clip is pretty annoying. The retaining clip is a real S.O.B. to try and spread apart again. I learned a little trick to make it easier to get it back on. First examine the actuator buy pulling up the thin rubber guard and note how it is mounted to the clip. You will see two small shallow round dowel like things sticking up on the side of the actuator body.The retaining clip snaps over the little shallow round protruding things on the actuator body, I do not know what they are called but you will see them when you take a peek at how it mounts on. While getting overly annoyed I ripped of the thin rubber water proofing boot and have not had a problem at all. The rubber boot works against you when you are trying to see where the little round shallow protruding things are at that I mentioned earlier.
You want the threads of the small bolt protruding out so you can push it through the original hole where the rivet used to be on the outer side of the door.
Once I got the threads to protrude out of the hole I quickly put a thin free running 10 X 32 nut on. Do not use a lock nut..you will be battling with the bolt spinning around and working against you. You might want to put a little locktite on the threads.. I did not ...I just made sure it was very tight. I check the tightness now and then and it has never been loose.
I wish I could give you the exact size of the bolt and length but it has slipped my mind. I am quite sure it was a 10 X 32 5/8ths inch long and a thin free running 10 X 32 nut.
When you are holding the actuator and retaining clip in your hand you will know exactly what you need. Just do not get too long of a bolt because when you mount it all back together and the threads are running through the nut and is pushing against the door you are going to need to do the work all over again and I know you will not want to do that !!... I did not laugh too much when it happened to me and had to put in a shorter bolt.
Just use your judgement and think of keeping the length as short as you possibly can and have enough length to get it through the hole and mounted.
If worse comes to worse you can always file down the length to make up for the clearance you need for the door to close properly.
The rivet is pretty big and you will need a heavy duty rivet gun and you will need a hand having someone holding the actuator and another trying to pop the large rivet.
Good Luck...I hope this helps.:salute:

Thanks Rick. I'm not looking forward to tackling this one! I'll definitely follow your post as guidance.

Cheers.
 






Your welcome Celly;

Be very careful inside the door especially around the actuator area there are some very sharp edges in there. WEAR GLOVES

Removing the glass run channel makes things a little easier.

Disconnecting the power connector at the bottom of the actuator is a little tricky because of the connector clip lock. If you break the clip lock tab make sure you tape it secure. If you dont tape it you will be pulling the door panel off now and then to connect the electrical connector back together. That always happens when the temp is in the teens with a 30 M.P.H. wind :mad:.

Take care Celly
Rick
