Replaced the driver's side door lock actuator on the 100. Now all the door locks are working correctly.
You certainly aren't saying this is a issue on the 100 series are you?I have a bunch of the small motors that are suppose to fit this. My 99 4Runner as acted up once in the heat. Figure the easiest fix is to not go outside during the day in the summer.

Yes, If you consider some going bad after 10 year an issue. The warmer it get the more problems you will have. It would be easier without sweat running in your eyes.
I have done all 5 100 series locks in the past it not bad just take you time on the plastic clips that hold the linkage.

Mine had the same symptoms, in the heat none of the locks would unlock. At times, I had to crawl over the back seat to manually unlock the tailgate.
Good luck.
It took probably an hour and a half. I would guess after each door, they will get a little quicker. I replaced the entire actuator assembly, not just the motor. I was not sure which motor my 100 has. I now need to take apart the old actuator and see which motor I have. Then I will order 4 motors.
Phil is correct, the hardest part is getting the plastic clip out of the linkage. I cracked mine, but put it all back together. I think I read on MUD somewhere that you can order just the clip, but I think you have to search Celica parts.
Not only did I take off the inner door panel, I also had to loosen the outside door handle. That helped remove the plastic clip from the linkage.
I am hoping that I only HAVE to do the drivers side for now. It seems to have worked, but only time will tell.

Can't afford Snap-on; and besides, if I came home with a snap-on hammer I'd never use it. You are not a real TEQ head if you allow Phillips screwdrivers to touch your JIS heads.
