ok when its on ac the four frount rectangluar vents work (the ones in line with the radio). Then when i switch over to heat the top and bottom come on with no heat. is that the way that luminas work. i just got the car for cheap and i'm trying to work out all the problems. I got four wires that were cut and connected together which i think went to the air low/high pressure switches. I still need help to find where they connect. So if you know please help.
thanks
