Why The passenger side sliding door opens fine but when it close it just bounces back open i would have to manually push it to close?

The issue with the passenger side sliding door bouncing back when trying to close could be due to a few reasons: a misaligned door track, an obstruction in the door's path, or a malfunctioning latch or sensor. If the door track is dirty or damaged, it can prevent the door from closing properly. Additionally, if the door's sensors detect an obstruction, they may cause the door to reopen for safety reasons. Checking for any visible obstructions and inspecting the door's alignment and mechanisms can help diagnose the problem.
