Not a major problem, but is annoying. My passenger rear door lock/unlock doesn't electrically engage & thus will no longer lock/unlock! All the other doors lock/unlock as normal.
Is it the door lock likely? Actuator?
Check ecu-1g fuse in dash fuse box first as that is for pasenger door. It can be the module in the door or no power going to door lock and that must be checked first. Make sure your door lockout on drivers sides isn't engaged. There are also a coupleof switches that are connected to door key lock that may be bad. So try moving thekey on the passenger door to lock then unlock and see what happens
