Hi all,
I have a 1997 C3500 crew cab with a 6.5L, with the dreaded dome light and cargo light issue. I have done some trouble shooting.....
The cargo light switch has power at the orange wire, the switch is working correctly, and has good ground at the cargo light (the interior white ground wire), the brake lights do work, there is no continuity between the blue/white wire between the switch and the light. I can get the cargo light to go on by jumping 12V into the blue and white wire at the cargo light.
The same is true with the dome lights, I have a good ground, I have 12 V at the orange wire under the dash, the orange wire does not have continuity with the wire under the dash. I can get the lights to come on by jumping 12V at the contact with the orange wire at the lights. All door switches are working appropriatly, and all bulbs are working.
.....it seems that both the orange and blue/white wire have been cut somewhere. I have not pulled the trim down to look at the wires, is there a common place where both these wires can be cut? I'm not blowing fuses, so i dont think it shorting out. I'd rather not pull down all the trim, it is somewhat brittle
thanks in advance
