I have found a wiring diagram for my truck, (95 K1500) for the interior light circuit. All the grounds come to a location G202 (Left I/P) where is this? (Page 4-96 of the GM Wiring diagram book)what does I/P stand for any input to this? All the other notes make sense just not this one. I have seen there are several people without interior lights and maybe this is one step towards finding the cause. What I have found so far is that I am not blowing fuses so its not power issue, it is confined to the courtesy lamps and is a ground problem in this circuit. Now If I can figure out or someone knows what I/P is and would let me know I could maybe work it back and let you know how it goes.

thanks for the input.
Shaun.

 

Why not pick up a ground at a different location? Any frame or body location should work. I've done it on tail lights, just use a self tapping shooter screw, screw it into the body or frame, a sta-kon fork or ring terminal to the screw and splice it in to the ground/ common wire.

 

I\P = Instrument Panel

 

Shawnvw cool, I/P that simple? I was at interior panel, I_ _/Post, but instrument panel just was not there for me.

Sparks134 yup that's whatI'll do once I find which ground to what light or switch has given up.

I'll let you know how it turns out.

check the groung wire under the carpet. it runs close to your heel. sometimes it breaks with time.ask me how i know.lol,lol

 

That sounds good, I haven't found that one yet. Apparently grounds are every where, it's a matter of finding them all and figuring out which one is for what. Kind of reminds me of Lucas wiring, the phrase "Lucas means darkness" has great meaning.
