'04 Power Locks: All Lock, Only Driver Unlocks
 

I've been scouring the internet for help on this. If anyone here can help with this, I'd be so pumped! Here's what's going on...

The driver door will lock and unlock as normal, but the rest of the doors ONLY lock. If all of the locks are unlocked (manually reaching over to each door and flipping the sonofabitch myself) and I try to lock them, they will lock.

The (minimal) Troubleshooting I've Done:

• Replaced driver door lock/window panel. Made no change.
• Replaced FOB battery. Made no change.
• Sometimes, very rarely, if it's cold enough (I'm in southern Ca) all of the locks WILL unlock. This leads me to believe it isn't an actuator issue.

My guess is that it has something to do with the ECU, maybe a bad/broken/frayed wire somewhere. But I'm not great with schematics and unsure where to go from here. Help a Camry owner out!

Oh! If there's another thread that's answered this, I'm sorry for being redundant, please just post a link!

This seems a common issue linked to the door lock ECU. Something to do with moisture. The fix a replacement.

I have discovered that alot of Toyota Camry's of this Generation(2002-2006) have a specific door lock problem that develops. This problem occurs when an internal part of the Car Computer/Fusebox under the drivers dash burns out. This results in all the doors locking, but ONLY the drivers door unlocking. You loose the Unlock function of the Passenger side door and both rear doors. If this is your specific problem, then Toyota's ONLY Fix to this is to replace the Car Computer/Fusebox at a cost to you of $700-$900.

I have designed a Module to bypass the burnt out internal parts externally. There is no need to remove the Car Computer/Fusebox from the car. I include a detailed install guide that is COLOR CODED with PICTURES. The Bypass only requires 7 connections. I include all the needed connectors to make these connections.
