I HAVE '97 E320 W INFRARED POWER LOCK SYSTEM. THIS MORNING I COULDN'T UNLOCK THE CAR FROM THE DRIVER'S SIDE. WHEN I WENT TO THE TRUNK, WHERE THERE IS ANOTHER INFRARED SENSOR IT UNLOCKED. WHAT DO I HAVE TO CHANGE ? JUST THE SENSEOR ON THE DOOR /RED-GREEN WINDOW/ OR THERE IS SOMETHING ELSE ???
PS DO THESE CARS BRAKE SO OFTEN ? I CONSTANTLY HAVE TO FIX SOMETHING !
