I dunno if it's just my car being plagued with electrical problems, but sometimes the power locks work, and sometimes they don't. I bought my car used so I don't know exactly how the locks work, according to the manual... but I find that usually, if I try to lock my doors by pressing the switch on the driver's side, it snaps all the other locks OPEN if the engine is running. If I turn off the engine, hitting the switch only locks MY door, but for some reason, if I use the switch on the passenger door, it locks ALL the doors. Is it supposed to work this way? My doors seem really inconsistent... sometimes, I can get all the doors to unlock if I use the key from the outside of the passenger door, but sometimes, it doesn't work at all.
