Question about Cars & Trucks
My door locks are locking and unlocking themselves while driving down the road on my 2006 honda accord. I've had this problem on a van once before and it was the body control module. Can this be remedied temporarily by just unplugging the fuse to the locks and locking and unlocking the doors manually?

I am a mechanic and had the same problem with a 2005 Acord that I purchased couple of months ago. Contact through the trade provided little help. The problem arose during a week that we in Adelaide, South Australia had a record o 40+ degrees centigrade heat. I noticed the drop knob slightly moving when the immobiliser was activated, but the drivers door failed to lock. Key locking would lock all doors however.
The cost of a door actuator from a Honda dealer was $185.00 (Aus), about $250 (US). The spare parts guy told me they had them in stock and sold a number of them. As a result I decided to find out whether the actuator was in fact faulty. I susequently removed the door lock and actuator assembly from the door. (A fiddly type job). The actuator assembly is in a plastic sealed assembly. By using a lot of patience and a box cutter I was able to cut around the assembly and then carefully lever the plastic housing apart. This revealled the small electric motor (similar to a slot car motor) that drove a worm and wheel assembly and a system of cams that actuated the door lock system. I found on dismantling the electric motor that the armature was coated with grease from the wormwheel /cam assembly that is mounted above the motor when installed in the vehicle. I cleaned the armature and brushes using superfine wet and dry carborundum paper, undercut and cleaned out the two armature segments of all remaining grease with a solvent. The motor was then tested with 12 volts and found to be ok. I then reinstalled the motor and glued the housing back together. It now works fine. I believe the housing was either initially overfilled with lubricant or that the high ambient temperature caused the grease to melt and flow into the elecric motor contaminating the motor. (There is no seal between the gearbox and the electric motor). The job took a few hours from start to finish but I saved the cost of purchasing the part and didn't let it beat me.
Cheers and beers

You need to have someone or yoursef check the body control module with a compatible scan tool. Thats where the problem you are having resides. It may need a software update or replacement. You can also disconnect the battery for a few minutes, that will cause the BCM to reset and may fix it.

You will probably need to replace the power door lock actuator.
Here's a link to one similar to yours.
You can probably get a used one from a salvage yard.

i have replaced many sliding door lock actuators on these vehicles..dealer part..mostly on passenger side sliding door..also possible you have a broken wire in door track harness..follow wiring from door into what looks like a plastic chain in door track at door opening
