Hello from NZ, I love my recently purchased 1998 RX300 but mine has developed a problem with the auto door lock. Whenever I reach 20km/hr it clicks 4 times as if it is trying to lock or unlock the doors which is very annoying. The remote door fob will not unlock the drivers door but works on the rest of the doors. When I park all my doors are locked and have to switched to unlock. Are these problems related and can anyone help me problem solve this?
