The automatic door lock on my 96 Honda Accord makes a loud buzzing sound when locking. Is there anyway to fix it myself? How do I take off the door panel to

My 1996 Honda had the same thing on the driver side door.

It was caused by a deteriorated rubber stop inside the door lock actuator module. The module is buried down in the lower outside corner of the door. Inside the module there is a track on which two electrical contacts slide along with the actuator, and a small rubber bumper stop. When this stop deteriorates, the contacts over travel and run off the track. Evidently this confuses the actuator controller into oscillation. The control module limits the time this occurs, so the buzz stops after a short while. There is somewhat of a spring return action to the mechanism, so the contacts return to the track, making things good again.

The dealer couldn't get just the rubber part, so $130+ for the whole module. My make-shift o-ring replacement only lasted a few months.

Definitely a chore to get the module out and back in.

Sounds like a bad solenoid. Check my door panel removal solution.
