My front passenger side door lock make a buzzing noise everytime I lock it. All the doors lock but it makes that buzzing sound as it locks. What is the problem?

THE SOLENOIDS MAKE A BUZZING NOISE WHEN THERE IS AN OBSTRUCTION.

king mechanism faulty and needs repalaced check to see if it locks

Sounds like the linkage may have been detached when the mirror was replaced.

Behind your door panel and behind that canopy cover which is plastic. All the way to the door locking striker or door latch which fastens the door closed when shutting. By and below this is a cylinder which has a steel rod running from it to your door lock indicator which you see that goes up and down when you lock your car. This electronic lock has failed and seems to be stuck is why the buzzing sound is . Replace this your problems will be over. Please rate my solution it is how i get my achievements Thanks

You should replace power door lock at front passenger side, you can use any 'universal' power door lock. its an unit with a small motor inside that have a mechanism to up and down according electricity from the actuator (master door lock at driver side)
Hope this help :-)

You have a common proble. Replace the control assembly. have replaced several with the same issue.

You'll need to replace the solenoid (motor) that doesn't work. Not hard once you get the door panel off. I suggest you buy the correct part, not a universal one.

The problem is caused by the electric motor that operates the power lock in that door, this motor is inside the door and will need to be replaced to correct the noise issue..

ok ur door lock switch isnt going out,,however ur drivers front door lock actuator is going or is already bad...have that replaced..also as far as the end noise buzz u hear , that may be ur a.b.s modulator and accumulator cycleing on and off..it may be empty and or leaking..have the a.b.s modulator and accumulator checked at the dealer..its an expensive fix... ur modulator unit in in the front left or right of the vehicle depending if u have a v6 or 4 cyl. its a square unit with a rectangular brake fluid resevroir and a long tubular cylinder (acummulator)... also identify it by the orange connectors...and the brakelines going to it...common symptom with those accords....they leak alot especially if with high mileage..

thei are screws in the door hidden by caps that you need to take off the door and near the mirror shoud pop off
