Hi everyone,

Seems to be a slight electrical glitch with my passenger side door in the back. The window is fine, unaffected, but there is no power lock to that door whatsoever (if I lock one door manually, all three lock except this one). Also, if it is the only door open the lights and the turn signal sound will fire hectically until it is closed. Does anyone know what's happening and how I could fix it?
Thanks in advance! I'm learning a lot about this car, it's my second car and the only one I'll ever care about.

 

Hi Malihide,

You might first check is the wiring harness between the B-pillar and the front edge of the door for any signs of damage to the rubber gaiter or the wires inside.

The next step may be to remove the door interior trim (not hard) so you can test for voltage at the door lock actuator and inspect for other problems. Sometimes the door actuators and linkage sieze up and need to be lubricated and/or adjusted, but it sounds like your problem is electrical given the weird security system behavior.

Hopefully others will have additional suggestions.

Cheers,

Don

 

Didn't I recall reading about some weird issue with the lower door red "pool light" and bulb that would sometimes cause disco lighting like this?

I thought I read about someone pulling the bulb in the interim. That might be a clue and place to also look.

"Puddle light", Al! Though I think that is a funny name to call it, right?

Malihide, the flickering lights are caused by the door latch switch in that door. First try removing the puddle bulb like Al said. That will end the disco light show. I don't know if that will also cure the dead door lock mechanism, but I doubt it.

You can either live without the puddle light on that door, or if you go after the dead lock, you should be able to access and clean the microswitch on the latch, after which the lamp will work properly.

 

Thanks everyone!

So I took a better look, and there's no damage to the gaiter at all. I think this door never got enough use, and I'm betting on the actuator being the problem.

The puddle light... That's the red one on the bottom of the door, right?

I'll pull it off and take a look. I know there's plenty of guides here so I won't ask...
