I'm having a problem with the front passenger electric door lock. I've been told that it may be a problem with the actuator. But just to be sure I'll describe what happens:

1. Using the keyless lock, only 3 doors lock/unlock; the front passenger door does not.
2. Using the key to lock/unlock from driver side, same thing.
3. However, using the key to lock/unlock from the passenger side, ALL 4 DOORS lock/unlock.

Do these symptoms identify exactly what's wrong? Or, if it could be a couple different problems with the door lock mechanism, what test must I perform once the door panel is removed? Do I remove only the top interior door panel, or the bottom one too? Assuming that the actuator is bad, is replacement of the actuator a simple, straightforward job? Does the passenger side take the same parts as the driver side? Do I have to buy the part from Mazda?

I'd like to try to fix this myself if it's not too difficult. Mazda dealership quoted about $300, another shop $209. I read a post about this topic on this website from a long time ago, but I just had a few more questions. Thanks for your help!

So far so good. I've got the door panel off and just waiting for the new actuator to arrive. I'm a little unsure about how to proceed though. Do I disconnect the entire locking mechanism at the door jam? and then pull it all out, detach the lock mechanism from the actuator, then replace it? Or can I replace the actuator without pulling everything out: i'm not too sure about this option because it's pretty tight quarters in there. Thanks!

 

I am also having the same problem with my drivers side door lock actuator.

Has anyone posted diagrams or phot0s on how to remove the door panel and then access and replace the actuator.

Thanks,

Why don't you guys try lubricating the mechanical parts with silicone before spending money on new actuators?
