Hello: I just bought a 2007 Tahoe. Everything seemed legit when I bought the Tahoe. The battery was dead from the previous owner letting it sit (so they say). I got it home. Bought a new battery. Started to notice the interior lights are pulsing and the two circuits. under the dash are hot. (See the picture where they plug into the junction under the dash.) I removed the IS LPS (Interior Lamps) fuse and the pulsing stopped as well as the overheating of the two circuits. However, I am losing the manual on/off of interior lamps as well as lamps for gauge cluster, HVAC cluster, visor lights and other similar illumination. The dimmer switch and automatic on/off of the interior lights still work since they are on a separate circuit. As I have continued to investigate this issue, I noticed the sunroof switch was not factory. I called Chevy and they told me this VIN number did not come factory with a sunroof. I found the power source to the sunroof and disconnected the fuses and this did not fix the problem. I wish they would have run power wires to under the hood power source to the 30A fuse, but they did not. Anyway, removing the power source to the sunroof did not fix the problem either. Does anyone know what diagram and where these wires run that are shown in the picture below
