Help Front Left Window regulator replacement

[mohan]

ok..Before I try to cut the cable..wanted to give the other suggestions..Here is what I find..I think the left side of the glass appears to move freely..the right side of the glass (bottom) is where it is stuck or jammed..I have been little bit gentle as I don't want to break the glass..does that shed any clue..Also looks like the left side the screw seems to be off..looks like the previous owner or whoever did the job tried to salvage whatever was there..
If I snip the cable will the glass come off or slide up easily? Thanks..
