Honda Civic EX 2007. Noticed that the locks on the car stopped responding to the automatic remote when it was cold and/or wet outside. I initially thought it was the remote that was the problem, so I took it apart and cleaned it. After some testing came to realize the remote is fine...it's some kind of wiring around the lock in the car that has the problem.

Was able to use it until recently when the car was in a dry or warm environment. As soon as it started raining, or if it was very humid out, the door stopped responding to the remote. Now it just stopped working altogether.

Anyone had a similar problem? Honda dealership wants $200 just to diagnose the electrical issue.

Thanks in advance.

Probably a broken wire in the drivers door going to the master switch.

$200 is not that bad. ...even with a pretty good understanding of electrical trouble shooting and a good diagram, it is a pain in the *** to trouble shoot that circuit.

I think it took me about an hour to trouble shoot mine, run a new wire and reinstall the door panels I took off the drivers and passenger side.

You can try it yourself, it's not exactly hard just tedious.

Start by checking the related fuses and relays.

You'll need
-a roll of multi strand wire
-soldering iron/solder/extension cord/electrical tape or thermal shrink wrap
-a multimeter
-wire diagram

It's also nice to have

-a test light
-a second battery to test jumping/motors

Thank you. And it does sound tedious. Maybe I'll pay the $200.
