My 1997 Honda Accord EX power door lock makes a loud grinding sou

i have a 1997 honda accord ex. i have a knocking noise in the front end up to 25mph and goes away until you hit about 55mph then it comes back but it also goes away with the slightest turn of the steering wheel. what could this be? please help me, i been stuck on this for 5 days now. thanks.

this sounds like the power door lock motor has a problem and will have to be replaced.

The door lock actuator in the door that is making the sound is starting to fail. Replace the lock actuator for that door will help.

You can usely find the parts on eBay easyer then the regular parts stores...I looked for these before...they are ready available...

This is something you have to remove the door panel to before you can say what it is. But I don't advise a DIYer doing it because its a little tricky. I recommend taking it to a body shop . They do this stuff in their sleep let them deal with it. If you try it and mess up then you have no door lock. This is not a big repair.

if u switch it on the motor should make a noise then the motor is ok/ check fuses / the switch and the relays....

Sounds like a sticking switch ( actuator ) in the door.
Pull off the door panel and , looking inside the door, follow the rod from the key to the actuator .
Clean the actuator and make sure it works freely before re assembly.

u got bad door lock actuator

it has a solenoid in each door that locks the door when activated make sure you have power to and ground from the solenoid if so replace the solenoid in the passenger door
