I was wondering if anyone knows the part # of this.

On the driver side arm rest. The console where the power door locks/window control are. There are two metal clips that hold it in place. One is missing. This console is now loose.

Does anyone know the part #.

for a pontiac Grand AM SE 1999

All the part #'s are listed for the 99-03 Grand ams in the Tips and Maintenance subforum (http://www.automotiveforums.com/vbulletin/forumdisplay.php?f=2148).

Pretty sure the window button bezel is in this particular thread.

I think this is that part,
11 retainer - 99-03 B GM#22603516

But You may not need a new clip.
A lot of the time it falls inside the door panel and sticks to the speaker magnet ;)

We have the procedure for that in the N-Body Appearance-Non-Performance (http://www.automotiveforums.com/vbulletin/forumdisplay.php?f=1988)

Hope that helps.
