Did you ever get this figured out? I have a 1995 K2500 Suburban. Some of the dash lights went out so I decided to replace all of them. I've only had this particular Suburban for about a year so I'm still finding small things here and there. When I got to replacing the lights in the HVAC control I noticed they'd been screwed down into place and the panel itself was fractured and in pretty bad shape. I can't seem to find a replacement panel in decent shape for a price anywhere near reasonable. I do however have at least one spare from one of my previous trucks ('96 & '98) along with the connectors and pigtails. I assume the color codes are the same and it should be a matter of just matching them but I don't want to just start cutting and get halfway through before I find out I'm wrong.
