2001 Pontiac Grand Prix SE (Sedan), 125,000 mi., 3.8 6cyl.
Issue: Driver's side front window had intermittent working issues, then stopped working altogether. All other windows work. So far I've replaced motor (came with regulator), and the switch but to no avail.
The problem seems to be (I guess) a bad wire. If not , what would you think the problem is; If so, how would I troubleshoot which wire it is and further, is it possible just to replace the one problem wire?
Your help is greatly appreciated.

CHECK TO SEE IF YOU HAVE POWER AT THE WINDOW SWITCH WHEN PRESSING BACK AND FOURTH IF NOT THERE IS A RELAY BEHIND THE GLOVE BOX , SWAP IT OUT WITH ONE JUST LIKE IT AND SEE WHAT HAPPENS
