OK, my passenger inside door handle kept coming loose from the actuator. I went to the dealer and bought a new little white clip for it. (Cheapest part EVER on any car BTW, $0.52) Seemed to fix the problem, until today, came out again. This time when I went to re-attach it the actuator bar came out of the clip on the inside of the door. Then the clip fell down into the door, between the door and the inner panel. So,...3 questions:
1. How easy is it to remove the door panel?
2. Anyone have a permanent fix for this problem?
3. Why is it the passenger (lesser used) door?
Thanks
