1990 Accord - Power door locks

[Eric Drew Hollins]

Ok, so I have a 1990 Accord EX coupe. 202K miles on it.

This is my problem. My power door locks won't work. The problem started that it wouldn't work very intermittenly. Then, the problem became more and more frequent. Then, the problem became that they would only work maybe 2 days in 2 weeks. Finally, they just stopped working. Also, this happened with both door locks. If one would work, the other would work. If one didn't, the other didn't work. This led me to rule out that the individual switches were dying. Maybe the master control switch or a solenoid is out? Also, my power windows work fine.

So, I have found a guy on ebay that is parting out his Accord. I am thinking about asking him for parts to fix my power door locks, but which parts do you think are bad? What parts do I need to replace to get my door locks to work again? Thanks.

Does it make a difference if you are using the switch in the driver's door, using the key in the driver's door or using the key in the passenger's door?

Nope. The door locks will not work from any of those locations. The power door locks are completely dead and all ways of accessing them (driver door inside, passenger door, driver door outside) went dead at the same time. Thanks.

You need a new door lock controller. It's in the drivers door. About $100 new from Honda Parts.com I had this same problem a few months ago and didn't want to spend the $100 as I wasn't sure if that was the problem. I got one at a junkyard for $20 and it fixed the problem. No parts stores carried the part, I could only find it at the dealer.

If your power door lock controller is mounted inside the driver's door as on other Hondas I have seen, I would check if the battery and ground connections to it are good. It is not uncommon for some of the wires from car to door to break after 14 years of opening and closing the door.

Mine make a noise for all 4 but don’t work the fuse was blown so I swapped that and it gave it power but still not functional
