Door central locking not working, Honda crv 97

SOURCE: 2004 Honda Accord Euro. Central

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

try testing or replaceing the drivers door lock actuator, reprogram ur key fobs and try unlocking and locking ur doors. as far as the lights and reminder,....it sounds like a seperate problem. but try the door actuator first (drivers side always act up and cause every other actuator to act up... like a bad kid that gets the rukkus started and ruins things for everyone..

you may need to replace the door locking actuator, they do tend to go bad over times. does the driver side door lock automatic when using the lock button on the driver side. if you can lock and unlock the driver side door with a switch, my guess would not be the locking actuator, it might be in the remote locking module.

Testimonial: "Thanks for the help. everything relates back to the actuator.."

Hi I wonder if you can advise me ,my central locking and alarm is very unreliable it keeps making a beep before the ignition goes on and clicking,it sometimes sets the alarm off,Ive had the AA round and theyve told me the car battery is dead,which I appreciate,but think the key hub central locking or alarm is running the battery low does the hand held button need a new battery,or can I take the fuse out for the central locking,dont want to pay 66 quid for a new battery if I can pay 2 quid for a new battery for the central locking button,or demobilize it
