At my wits end, 2000 SSEI drivers side window controls not working, others 3 windows work, Read a post from Srsauder back in 2013 same problem and tried every suggestion posted at that time. I'm going to assume it'* not the switch pack unless all failed at once.
I tested the the plug to the drivers door module (ddm) the 2 orange wires have 12 v, and 1 of the 2 black/wht have good ground. took out front seat / all wiring under cartpet like new, What i'm missing?

I've had the "well-known" rear windows failure - but the front ones never had that problem...

Check the loom between the pillar and door. They break from being opened and closed.
