None of the GM window switches have a black wire nor a ground. The ground "path" is a separate circuit. The switches simply reverse the polarity as I previously stated. Five wires for the master switch and 3 wires for the passenger side. It's possible you have the wrong switches or Painless uses a design that's different from GM's. You should contact Painless and obtain a schematic for their harness. Their harnesses require some knowledge and "engineering" when installing. I've seen very few of them that were 100% plug and play.
You let the smoke out of a component?? That's not a good sign, the component is now probably bad.. What about any damaged wires?? When testing such as you conducted, use fuses, and/or circuit breakers for component and wiring protection and use a light bulb as a load.. You can't just randomly connect wires "to see if that works"..
Here is a link to a forum website that is packed full of electrical stuff - diagrams, troubleshooting, circuit tabulations, etc.. Scroll down past the circuit tabulation charts. You'll find several wiring diagrams.. In those diagrams is the diagram for power window circuits.. Wire colors, connector identification, etc..
