Hi all, New to forums. I have a 1999 GS300 (great car) and the driver's side door actuator is not working (it does not lock with the remote, only manually/mechanically when the key is used) Does anyone have one or know where I can get one (besides the dealership)? I was contemplating buying one from the US but then it occurred to me that their passenger side one will probably be different than our driver's side one (the right door). Thanks in advanced.
