2002 Acura MDX door lock fuse blows

Acura what ? MDX , NSX , RL , RSX , TL , TSX ? Probably a faulty input to the BCM - body control module or what ever module Acura uses to control the locks with . Could have DTC - diagnostic trouble code stored .

The remote may have to be "re-trained" to your vehicle. The owner's manual should have the process listed. Probably having to sit in the driver's seat with the untrained remote while working the lock controls on the driver's side door.

Check fuse and/or relay to see if blown/non-functioning. Should be labeled door lock or dr lock.

Tires and locks are unrelated. First I have the codes read for the BCM, then I would go for the drivers door. At the door jam in front, there is a boot that holds the wires. Check for broken wires here first. The go to the hatch and check for broken wires in the boot at the top. Codes will tell you which latch is bad. Go for them also.

Bring to an Authorized Acura Dealer, It usually a sequence of buttons that need to pushed in a precise order.

Hello,

Sounds like the actuator has gone bad (replace - may be some videos out there on youtube)

I hope this helps

It sure sounds like a fuse may have blown, although the cigarette lighter fuse in most cars does not control the radio, and should have been able to handle the car charger without blowing. Take the lid off the fuse box, either under the hood or inside the car under the dash on the right side or left side of the car, and look for a blown fuse. Usually you can tell if they are blown by looking at them.....but you often have to remove them first, depending on the type of fuse used in your car. The inside of the lid may have a chart that shows which fuse controls the radio.
Good luck,

Take off the trim panel and see if you can see the servo that controls the locks push rod. It may have been disconeted, or broken, the ends are usually made of plastic. Also you will be able to see if it is even actuating when you press the lock/ unlock. Good luck!
