How do you replace the panels on the outside of a 1995 pontiac Grand am?
Same as any other model year. I did it with my '95. Ordered the part via ebay. I did not need to, nor did I take the door apart from the inside of the car. Basically, just unscrew/unbolt the visible bolts on the interior of the door frame with the door open. I had no knowledge of how the thing was assembled, but had it replaced in about 20 - 30 minutes.
When you open the door, on the inside of the door (the part where the door striker/latch is) there's bolts you remove. It seems to me there's a panel that runs along there as well that you have to remove. My old handle broke so I just pulled the remains out from the inside of the door. Start by removing that panel on the door frame, and look for it's bolts. Buy a Haynes manual if you're still confused.
