'98 Accord - power door locks not working

[john_diy]

Hi,

Since yesterday the power door locks on my '98 Accord LX (Sedan) are not working. I noticed that it happened after I started the car and it died on me. I tried it again but this time with my foot on accelerator and it started fine. I started driving and then noticed the locks weren't operational. They were fine before this episode.

- When I press the power door lock button on driver or passenger side nothing happens (usually it locks all four doors)
- Manaul locking is fine
- When I lock the car with key it doesn't lock all the door (it only locks the door I'm at - driver or passenger). This is supposed to lock all doors too.

I looked at the interior fuse box on Passenger side and the door locks fuse looks ok (#12). I also swapped it with passenger side power window fuse and the window still worked so I guess it's fine.

Any ideas on what I can look at next? I read the the actuator might be a problem (I don't know what it is but I'm willing to give it a shot). Looking at Honda Manual looks like there are multiple actuators (one per door I think) and it doesn't feel like everything would conk off together.

Any help is appreciated.

thanks,
John

I looked for other similar mails and also searched the web. Found something about resetting the multiplex system. I did the following and it worked!

Set Wiper Intermittent Control to medium, Put the key in, Turn to ON, OFF, ON. When I turned to ON I didn't start the car (just go to ON position in ignition). This fixed it:-)

What is the multiplex system and why did I have to reset it?

thanks.

I've been having a problem with the power door locks on my 1999 Accord LX. Started with the rear passenger door lock --- now both the passenger side power door locks are not working.

Tried reseting the multi -- mentioned in the note above - to no eval...

A ford (I know) mechanic said it was probably faulty actuators -- But what are the odds two go bad so close together...

Any ideas... Is there a way to find a honda accord wiring diagram online?
