My heater a/c control works the system fine, but the display panel is totally blank. I just installed it new from GM about 3 years ago. The screen has always gone blank from time to time, but now it never shows anything. I have checked the wires coming to it and the read battery wire is hot all the time; the brown wire above it is hot when the switch is on. Does anyone have any ideas what to check next?
