Window Regulator Problem? Or Height Adjustment

[korbeck]

Hey Guys,

Been registered to the forum for a while, but this is my first post.

This forum has a been great help and reference tool for my 01 Boxster. And I appreciate the resources available to me.

Since acquiring the car in March, I've changed the oil, and then replaced the Window Regulator and AOS.

My concern is about my window regulator. I bought a new one from ebay, assuming non OEM.

I replaced it, and the window functions perfectly up and down.

However, I did notice that when I finished the install the window was a bit high/tall. The problem is when I try to shut the door, the window doesn't drop and hits the convertible top roof as I shut the door.

Upon further inspection, I am able to physically push my window down when I upon the door (even if it doesn't drop). When I pull the handle, I can hear the motor engaging, but the windows doesn't move.

Trying to figure out the solution to the problem. I hate opening my door again (especially in this cold weather!), but if I have to I will.

Wondering if anyone could chime in for possible solution?

Suspects:
1) Regulator: Being a new regulator, I don't know if I can say the cable was "stretched". If it is defective I can always ask for a warranty exchange. However the windows work perfectly up and down, it just doesn't drop.

2) Window Adjustment: Is it possible that I can adjust the windows via the two screws on the bottom of the door? How mcuh adjustment can I do, and is this really the likely culprit? Since there are two screws, what do both adjust? I hate to mess with the factory adjustment of this really isn't my problem.

3) Window Memory? When I first installed the windows, they wouldn't go all the way up. So I rolled the windows all the way down, then held the button for whatever time. Then I rolled them up, then held them for a few seconds and it seemed to allow the windows to come up. But it didn't the window dropping problem when I open the door, and it looks as bit high. Am I doing these steps incorrectly?

I apologize for the detailed post, and hopefully I can figure out how to fix this. It's a bit of an annoyance, and I'm sure it's not healthy for me to keep slamming the glass against the convertible top

Thanks for your time, and I hope to become more active in this community.
