Not original sun roof buttons? 99 park ave ultra supercharged

[Synna]

I have these buttons on the left for the sunroof but it doesn’t look like any of the original buttons for the park avenue. I was wondering if anyone knew what buttons it came from. I have opened it but have no clue what asc is for, I’ve pressed it but nothing happened. Thank you in advance. I would also like to note that it won’t close either if you open it

Its for operating your automatic garage door. Look in your owners manual for programming instructions. I have it on my 2001 but never used it.
