Drivers side power door won't lock/unlock

I was told by a Toyota mechanic that the solenoid acts up when it gets hot. My 99 does it when it sits in the sun too long, but is fine now that the weather is cooler.

Hey folks, just wanted to revive this old thread. Today was the hottest day of the year, and my black 4runner was in the direct sun for over 4 hrs (only parking avail). When I got back to the the truck, drivers door wouldn't unlock. I envisioned the PITA of having to take off door panel etc, but thought I'd check the forum first.

Yup, hot weather was the culprit. After she cooled off, no problems with locks/key fob etc. Relieved, and thanks to the forum!
 
Lifesaver!

I'm glad I found this post. There's another one in the forums that must be for a different model or something, and it gave me a false sense of hope. Ha!

The write up above is good. I'll add my notes in case anyone does this same thing.

I got my replacement actuator from RockAuto. I think it was AISIN. The symptom was that when it got really hot out (~100deg F) and had been sitting in the sun, the actuator would only work intermittently. I decided to not mess with having my car only lock sometimes, and so I tore into it.

This repair is not bad, but you have to be patient. A couple of tips I wish I'd known:

1. There's a sensor/switch on the lock cylinder. I didn't see a way to unplug it from the cylinder. The wire gets in the way of the assembly when it's sliding in/out. I ended up disconnecting it from the door (a couple of clips) and then pushing it out of the way. Made things easier. It has a very stiff jacket that can be troublesome, and wants to route the wire where you don't want it to. Come to think of it, it would make removing the assembly initially easier, as well. Might was well get to it first off.

2. The second bolt holding in the door handle is accessible by using a deep 10mm 3/8" ratchet. You have to lift up on the door handle a little to give you a clear shot.

3. I put a roll of paper towel in the hinge area so the door wouldn't close accidentally.

4. The window track has a flange at the bottom (where you took the 10mm bolt out of that was on the outside of the door) that makes it hard to slide the assembly out of. You have to pull up on the track hard enough for the assembly to clear. When I went to bolt it all back up, it had been deformed a bit. It went back together fine, though, and the window works great.

5. The three star bolts on the latch mechanism are T-30. I had to run to AutoZone to get a set.

6. The main door handle rod (yellow retainer clip) is different from the others. The end has a kind of chamfered ball at the end. If you pull the door handle assembly out, you can see it. I tried prying and pulling initially, and I was afraid I was going to break something. Instead, I got a pair of mechanic's pliers with the two hinge positions, and put it on the wider position. I then put one of the jaw tips on the end of the rod, and the other on the "ear" of the door handle that it passes through and pushed it out instead, Worked much easier once you get it past the split retainer section on the other side.

7. I disconnected my battery. I figured that I'd be dealing with live wires otherwise and didn't want anything actuating or any of the security/alarm stuff going crazy with my hands in there.

8. When peeling back the sealing barrier plastic, the black tar sealer started getting stringy (it was hot in my garage). I used a razor knife to cut the black tar as I peeled the plastic back. I only needed to peel it back about halfway.

Good luck! Not really bad, but took some time and a fair amount of patience.
 
This happened to me today after I rewired my XM antenna. Then 2-3 hours later it went away....might pull of the door card soon and take a peek.
 
Hi guys, this is my first post, but I just wanted to give my experience with the same issue on my 2001 4Runner. Your advice on this thread helped a lot, but my problem was my actuator, not just a broken plastic clip. My actuator didn't actually have a yellow plastic clip. I'll attach a picture of the old and new actuator to show you.

I ordered the part (driver's front actuator) at my local AutoZone for ~$100. That was about the same at every place I called and close to the same as online. Plus I wanted to be able to easily return it if I didn't need it or if the actuator wasn't the problem, as it could have easily turned out.

Getting behind the door panel:
1. Remove screw for the handle. Slide the whole handle plastic piece forward until it is loose. It is attached to the metal rod that goes to the latch by a yellow plastic clip. Remove one end of that clip with screwdriver, needlenose, fingers, whatever. Slide the rod down and out of the clip and the handle will be free. This link is helpful:
How to remove the front door panel? - YotaTech Forums

2. Pull straight up on the armrest or use screwdriver to pry. It pops right off. Under that are two screws that you remove.

3. (I should have mentioned, this is for automatic locks and windows) Next use a screwdriver to pop the window/lock control panel straight up. Then slide it forward to get it loose. The wires are attached in 3 spots which are easy to remove with screwdriver.

4. There are 2 of those "plastic rivets" that you push in the center piece and pull out. They just look like a circle of embedded plastic. One is in the upper right corner of the door panel and one is on the left edge above the latch. Remove both.

5. Gently pry at the bottom of the panel with a screwdriver until the christmas tree plastic pieces pop out. You can feel each one pop and I think there are like 7. If you go slow, you can do it without breaking any.

6. Lift the door panel straight up. Up and over the lock knob and it will be free.

7. The weather plastic is usually sealed pretty well with a really sticky caulk. I pulled it slowly and used an exacto knife to cut the caulk. I only opened up the left half, because that's all you need to get to. At the end it was sticky enough to just smoosh back on.

Getting the actuator out
This was the hard part. I'll try to remember all the steps. It is mostly a pain because, as you can see from the picture of the door, the openings are way too small, so you have little visibility or room to work. Just yell out a curse word every now and then and you will feel better. :) (most of these steps are in no particular order.. you really just take things off until the actuator comes out.)

1. Take out the 3 bolts that hold in the door latch.

2. When you look at the door from inside, right where the actuator is, there are two bolts (you can see them in my picture). Take out the 1 bolt on the left. That is what actually holds the actuator in place.

3. Remove the plug that attaches the wires to the actuator. You just have to squeeze hard on the sides to get it free. You can do this either before or after the actuator comes out. It's actually easier after.

4. Underneath the latch, there is one bolt that holds the bottom of the window track. You will need to remove that. Don't worry, the window is still secure, it just needs to be all the way up throughout all this.

5. Remove outside handle/lock. I'm going to call this step optional because I know people can get to the actuator without doing this, but I found it really difficult to detach the two metal rods (one to lock, one to handle) without removing the whole assembly. If you are going to remove it, there are 2 bolts on the inside to remove, one on each side. The left one is much easier to remove if you use the hole in the door to access it. Once it is loose, you may have to remove the small metal clip that holds the lock in. Then detach the 2 plastic clips (mine were pink and yellow) that hold the rods to the outside door handle.

6. The last rod that can be removed is the one going up to the manual lock knob. You could probably get to the plastic piece and detach the rod like the others, but I found it difficult to access the clip. Instead, I unscrewed the lock knob and pulled the rod through the plastic sleeve as I removed the actuator.

7. The actuator should now be completely free. Put your hand around it and slowly pull it out and you get everything else out of the way. You'll have to make sure the 4 rods aren't getting snagged on anything and also bend the window track out of the way. Don't worry, the window track is fine once you bolt it back in. Bend it as much as you need to.

Replacing the actuator
The actuator should now be completely free. If I were you, I'd plug the lock/window control panel back in and plug your old actuator back into the wires (while it's all dangling free). That way you can press the lock/unlock buttons and if the actuator tip is not moving, you know conclusively that is the problem.

If it's totally shot, like mine was, replace the old with the new and do everything in the reverse order to reassemble. That was not as easy for me as it sounds, of course. :) For me, I had to do the disassemble/reassemble 3 times because the metal rods are finicky. If they got bent a little in the process your lock knob or inside handle could end up being a little sticky and you need to open it back up and bend the rod back how it was.

Anyway, wanted to give my story as someone with no mechanic experience to hopefully help others. Ended up taking maybe 6-8 hours, but I was learning everything as I went. In the end, it worked and saved us a lot of money.

Next up is to buy a remote keyless entry from eBay (our car didn't come with one) and program it to save the $250 the stealership wants for a single one (including the 20 second programming).

I'm glad I found this post. There's another one in the forums that must be for a different model or something, and it gave me a false sense of hope. Ha!

Bumping this since it was helpful for me while fixing my front left door lock actuator particularly the two posts quoted above. Since there are no step-by-step pictures, a lot of it you won't understand until you start disassembling the door.

One thing not mentioned in this thread is how to replace the motor inside of the door lock actuator. This is the part that actually goes bad. Instead of spending $100+ to replace the entire actuator you can buy a $6 small DC motor and it is plug and play. I just used a screwdriver to crack open the case where the motor is housed, swapped the motor, then used some dabs of JB weld around the perimeter to hold the halves together.

I bought my motor on eBay from MOPS Electric under the listing "FC-280 Motors with Collar - Car Door Lock and Mirror Motors - FC-280PT-22125". There are several variations of the motor and the correct one for the 3rd gen 4Runner seems to be the FC-280PT-22125 with short shaft and brass collar.

Got the new actuator installed BUT...

So it was a pain getting the old one out but it's out now. I tested it and it did not move at all when connected to the power door lock switch. I then attached the new motor to the switch and it was moving.sweet! Got the new motor installed and I hear the motor working but it's not locking or unlocking my driver door.How do I get the end piece on the motor that's actually moves the door lock installed correctly?? PLEASE HELP
I will be taking it back apart tomorrow
 
Bump.
It's back apart and I don't know how to correctly install the driver side door lock actuator so that it locks/unlocks door. PLEASE HELP!
 
I have an alternative method. Just got my fixed.

So I have an alternative way but thanks to your post I finally got it done.
I will write up step by step instructions when I get home tonight. This process does not require removing any rods or removing the outside door handle. Trust me it's still not an easy job. Step by step will come later tonight.

Did you ever write up the step by step for an easier actuator replacement?
