2004 LS430: 99K miles, took to dealership last Saturday to troubleshoot driver’s side door lock. Diagnosis...new lock assembly needed...no worries, wear and tear…good money spent. On Sunday, I start car to get some groceries and the passenger side mirror wouldn't unfold. When I attempted to unlock from the driver’s side controls, no response. Same result when trying to roll down window. The entire front passenger side is dead when only the day before at the dealership I was given a clean bill of health. Took it back to the dealership today and after 5 hours of troubleshooting, they're going to keep it and remove door panel on Friday for a closer look. Battery is good and no other problems to report with the vehicle. When you open the passenger side door, the interior lights won't even come on. When you open the rear passenger door, dome lights come on. I'm at a total loss...checked fuses and everything checks out. Car is garage kept. Until the driver’s side door actuator went bad, I had no problems with the car in the previous 30K miles. I would appreciate any advice anyone could share before I get taken for too much $$ at the dealer. Thanks/Steve
