@Hezath - here’s an example of what I refer to as “turnbuckle” adjuster, the first photo of the main rod (circled red) inside handle to door latch, in the second photo are these little screw adjusters act like “turnbuckles” are at various rod points to fine tune the latch mechanism.
The red circled item is an important spacer and guide for the main rod.
The door should have some spring effect when opened, your being so sensitive likely has to do with adjusting the rods.
There are 6 bushings for each door that attach to various bracket, if they are broken off or missing it makes it
difficult to open a door, bypassing the $2 bushings with an adjustment perhaps is the issue to compensate for sloppiness at one time under prior ownership.
Worth noting is the amount of “spring-open” your door has, if any of the door surrounding rubber seal is out of place, sliding off, obstructed, etc. that could add tension on the door that maybe causing it to spring-open” more so than driver side. Are all the door gaps level? Any resistance in shutting the door ?
You’ll need to inspect the entire operating with door card removed, adjusting can be tricky if anything doesn’t look right. So checking if any are bottomed or topped out would be are start. Check that springs are original and not swapped out replacements and l hooked onto the proper position.
It may be good to remove both door cards so you can get an idea of what’s what and starting point for how everything it working on driver side in comparison to passenger side door.
Let us know what you find. Good luck.
