The "automatic" door locks on my 96 Civic LX started popping open all by themselves recently. Doesn't matter whether the car's running or not or if the ignition is turned on or not. Thought it might be someone else's remote but the car does not appear to have ever had remote locks. Pulled the plug on the master switch on the driver's door and they still unlock themselves and then keep on unlocking themselves even though they're unlocked.
No voodoo or spells at work here I'm afraid. More like failing electronics I think and all of the locks still work easily and as expected (except for unlocking themselves of course) so there was no reason or logic to oiling them.
I don't have the owners manual and the map on the fuse box cover indicates a couple of possible fuses for this purpose but when none of them disabled the master switch I pulled each fuse and was still able to open and close the locks with the switch. I suppose I could have waited a while with each fuse out to see if the locks popped open on their own again but dismissed the idea as too time consuming and figured pulling the fuse wouldn't solve the problem anyway.
If the locks still open on their own when the master switch is disconnected, that switch must lead to a relay the "thinks" it's getting a signal from the switch and keeps opening the locks over and over again regardless. I'm assuming that there is just one relay because the only way to open all of the locks at once in this car is by using the master switch--the driver's door key won't open them and neither do any of the individual plunger locks on the other three doors.
