I have a 1995 Toyota Avalon. It is otherwise is very good shape but recently the passenger door has been responding to power lock/unlock with some “hesitation”. Pressing the lock button (through the remote or using the button on the door, or even using the key) makes that particular lock move just a bit but then it stops too short of actually locking. Pressing unlock right after this fully unlocks the door, and then pressing lock properly locks the door. This 3 button sequence, I guess, frees up the movement of the lock and allows it to lock in the end.
I am trying to understand why this happened and how to fix it. This is only for the passenger door.
The car is designed so that all doors are automatically locked when the car is put into D gear, and automatically unlocked when the ignition is turned off. However, a friend of mine has been consistently opening the passenger door just a couple of seconds before I turn the ignition off, which unlocks it manually. Can this, if repeated consistently 3-4 times a week for about a year, interfere with the power locking mechanism and damage it?
Another possibility is that it isn’t manually opening the door a couple of seconds before automatic unlock that has damaged it, it is the few rare occasions that both of us simultaneously operated on the door – him by trying to hand-open and manually unlock it while I was simultaneously turning the ignition off and thus power unlocking it. Is this more likely to have caused the issue, even though this has got to be very rare? (may be 5 times max, from what I can remember)
I would love to understand what caused it and what to avoid in the future.
Also, any ideas for how to fix it? Something I can do myself with a repair manual and tools (I’m ok with mechanical things, having owned a motorbike for some years, but don’t have much experience with cars, especially car doors and locks). If not, what kind of repair shop is best to take this too?
