Hello, I have a 2007 Honda Fit. I'm having some door locking issues. The driver door doesn't lock with fob but will unlock when it is locked. I can hear the motor working just fine. When i manual lock it with the power button inside it works just fine untill i do it a few times then all the doors will not lock. So i checked all fuses and relays relating to locks and didn't see anything wrong. I replaced relays 1 and 4 and the problem still there. Another issue is when car is on and locked as soon as the lights are turned on the driver door automatically unlocks. I have no idea what is wrong. I looked at youtube and a guy said the multiplex computer could go out? Any help will be greatly appreciated.

 

Strange symptoms! There have been recalls for the headlight switch and I believe one for water intrusion into the drivers door. Do you know if the recalls were performed?

I would bet that water has caused an electrical issue.

 

i went to honda two weeks ago for two recalls on the airbag and master switch were the only two showing up so i assume they have been done.
