My car is a 2002 GP GT coupe. The left door power lock switch works fine if I am sitting in the car with door closed and push it to lock or unlock the doors. If I open the door and push the switch nothing happens. If I use my key fob to lock or unlock the doors they respond accordingly. What do I need to do to correct the problem when the door is open? The passengers door power lock switch works as it should with the door open or closed. Thanks in advance, Bill
