Power lock/unlock issue

[johnsonnate]

So, I came out of work yesterday to find that my remote no longer locks/unlocks my doors. Tried replacing the battery, and using the spare remote and nothing. Alarm system works awesome, as does the rear window button on the remote.

As I have nothing to go on other than they doors not locking, any suggestions on where to start looking?

EDIT: I should also mention that the button inside works good, and I can put the key in the door and it works fine to unlock everything.

Update

So after reading some things on yotatech and here, I diagnosed the issue. One guy said that he had wires that were frayed in the loom going from the body to the rear hatch, and another guy said that he looked at the ecu in the rear hatch. I looked at the wires, they're fine; so I went to the ecu, turns out the main connector to it was a bit loose. Plugged it all the back in, it clicked, and everything works again!

Good man for updating

I know that there are a few threads in the 3rd Gen section that had this problem, and they were last updated like 7 years ago by the OP, and they didn't have a fix. So, I figured that other people will have this problem, might as well have a potential fix.

Side note, before I found the fix, I thought that it was the board in the dash that controls the window/defrost, and a separate issue from the door locks. So I found the part number for that board: 84014-35040. If anybody actually does need that board.
