I have a '00 Accord and there is a buzzing sound everytime I lock, and unlock the car. First, the problem was in the RR, and now its happening on the FR as well. I'm pretty sure its the door lock actuators. Has anyone had any problems with your pdl's ?

 

This is a problem w/ the actuator. It's constantly opening/closing very rapidly. It's an internal fault that I've read of others fixing by disassembling the actuator and repairing a broken plastic piece. I've never done this myself, so I'm unfamiliar w/ details.

You might try a search on this site for "door actuator" or "power lock". Also try a google search for "honda power door lock" or similar. I've usually managed to find what I need w/ a determined search.

good luck
