Hey! I've had that problem before! Just like Brent said, it's the little plastic clip that holds the actuator bar into latch mechanism.

I believe the part numbers are 89703 75090 for the left side and 89703 75080 for the right. They cost like $2 each, so I'd just buy both sides, so you have one when the passenger side breaks. As I recall it was a real bugger to get the clip installed without dropping it into the inside of the door. Good Luck!
