Hello
My 2004 Lexus LS430 rear passenger door won't lock/unlock anymore with my wireless remote. I have to manually reach back and push it for lock or unlock. It doesn't make a churning sound. I had a guy take door panel off and he used a machine to check power and found that a blue box panel with SRS on it with 3 connectors wasn't giving power to the acutator I believe. The window works fine and has power going to it. All wires are clean, everything is in it's place in very good condition. I just don't know what to do. I put an ad on craigslist here in Baltimore to try and find someone who can fix it ASAP. Club Lexus I need help

It may be the door computer / ECU. Easy DIY.

Most likely the door lock actuator as mentioned.

I have the same problem. ..sometimes. I thought it was cause I have a viper alarm and they hooked it up wrong. It did the same with the key alarm
