As the title says, It just stopped working. I had DIY installed the alarm shock sensor, and everything worked perfectly for two days. Then the driver's side door lock just stopped working.

I spoke to a mazda tech, and he asked me if the dome lights still come on and off when I lock or unlock the driver door. I told him yes, and he told me that the actuator isn't fried, and should still be working.

I've gone over the wiring three times, everything is correct. I don't know what to do, other than rip that piece of shit out, or throw 3-500 dollars at mazda to have them tell me I need to give them more.

Any ideas?

Edit: The shock sensor box says it was manufactured in 04, but the alarm works great, and so does the passenger door.

If you unplug the shock sensor does your door lock start working?
Does your door lock work if you physically lock the door with the lever?
Does your door lock work if you use your key?
Does your door lock work if you use your drivers side switch?
Does your door lock work if you use the passenger side switch?
Does your door lock work if you use the remote?

If you unplug the shock sensor does your door lock start working?
Does your door lock work if you physically lock the door with the lever?
Does your door lock work if you use your key?
Does your door lock work if you use your drivers side switch?
Does your door lock work if you use the passenger side switch?
Does your door lock work if you use the remote?

Holy cow.


If you unplug the shock sensor does your door lock start working? Not sure. Let me check...
Edit: if I unplug it, there's no change. Driver's dead, passenger works fine. Just no sensor.


Does your door lock work if you physically lock the door with the lever? Yes.

Does your door lock work if you use your key? Yes.

Does your door lock work if you use your drivers side switch? The switch? No. If I manually lock it, it stays locked.

Does your door lock work if you use the passenger side switch? Just the passenger.

Does your door lock work if you use the remote? Passenger, not driver.

Sounds like the motor in the drivers side door then.

Buy some electrical contact cleaner from Radio Shack.

Spray it in there and then use a can of air for keyboards.

Clean it. Pray.

Hmmm, I thought the motor and the actuator were one in the same?

Could be...didn't pull out the tech manual on it...but his theory on why it isn't the motor doesn't make sense.

Hmmm, I thought the motor and the actuator were one in the same?

(From the Electrical System Manual) "Door Lock Actuator - Contains a reversible motor which locks or unlocks door depending on the direction of current flow."

The actuator is controlled by the Keyless Control Module based on various inputs such as the door key switch, door lock switch, and Keyless (remote) Receiver.

I'd guess the motor is not sold as a separate item from the actuator.

Possibly one of the connectors, most likely the actuator connector or Keyless Control Module connector is loose?

Id have to look at the wiring diagram but I can't see the switch in the driver door going back to the Keyless module and back to the door to run that motor.

I just started having this issue today. The drivers door lock only budges a little, it won't lock/unlock via remote or switch.

Perhaps it's the heat?

I had this problem for a long time wiht the passenger door actuator..and took the whole thing apart to figure it out... the motor had just died after a while. The dealership will sell you the whole loking system for anywhere from $100 to $150, so I was quoted. I went to a junkyard and bought one for $40. You can search some of my threads and posts and find out what i'm talking about. It's a 9 inch or so black plastic piece...

I even tried calling the companies of the actuator, and the motor...both very japanese, and neither would help me out.

sounds like the motor to me too....
