Here is what I did to fix it. I took out the cluster and with very fine grit sandpaper (400 grit), I sanded the contacts. It worked on the driver's side contact (which was the most important one), but I couldn't get the passenger contact (behind the driver's side) to work. Not as critical since it has its own switch. I will buy some di-electric grease and see if that makes a difference with the contact.

I was wondering, is it possible to replace just one switch within the cluster and not the entire cluster itself? I tried to take out one of the bad switches, but I was worried I was going to crack the whole cluster, so I didn't.

I'm very happy though, that the drivers side window is working.

Thank you everyone!
