I have a 1993 s10 blazer, just put new window motors in and they still dont work. but i check the black wire on the switch which should be ground and when i push the switch to lower the window the black wire gets power. so when i ground that black wire to the door jam the windows work. does anyone have a idea what could be wrong?

I had the same problem - driver side fine, passenger side front not working/slow or the back seat. You need to replace the window motor on the passenger side. Yes, there are two motors. It's pretty simple if you are handy with some tools. The hardest part is getting the 4 mounts that hold the window motor to the door off. The are factory riveted to the door, so I had to grind the outsides off and tap them out. Just watch the spring lever that holds the window bar for going up and down. I didn't pay attention and it snapped back - nearly broke my thumb.
