Door lock problem

Post by shippingexpert »

I am having trouble with all but the drivers door. All four doors lock using the key fob, but the passenger doors will NOT OPEN. The solenoid sounds like it is working in 1 direction only. At first it was only the Front Passenger's door. Now it is all 3. I find it odd to think that all 3 problems would occur within a 6 month period.

Any help would be appreciated.

From the symptoms (door locks, but doesn't unlock), it sounds like the little red plastic lever in the lock mechanism is broken. See this link for repair details:

I have this same problem with one of my rear doors. I believe the cause of this lever breaking is someone (e.g. 5 year old child) pulling on the door handle at the same time as the motor is moving the lever to unlock it. Seems to be a fairly common problem. Unfortunately, the (proper) repair requires replacing the lock mechanism - about $100 for the part. The fix described in the link above looks to be a bit of a hack.

The only thing that would cause me to doubt this diagnosis is the fact that three of yours have failed in a short period of time. The red lever seems to break in such a way that the motor can still lock the door, but not unlock it. Listen closely to one of the doors that don't work, to see if you can here the motor moving when the unlock button is pressed. If you hear the motor moving inside the lock, then you can be pretty sure that the broken lever is your problem. Remember, if you use the key fob to unlock the door, all door locks other that the drivers door will only be activated on every second press of the button. Good luck. -Daire
