Dome and Cargo light not working

[randinator0702]

I have a 1994 gmc 1500 etended cab and my dome and caro lights are not working. I checked the fuse and bulbs and they are all good. i need your help what i can do thanks

Does the dome work when using the dimmer switch? If so then its your door jamb switches.

nope the dome doesnt work using the dimmer switch. I think it may be something in the wiring because my buddy has the same truck and the same thing is with his neither the dome or cargo light work no matter what we try so please help i need the cargo light especially for my job

Mine wasn't working at one time. After posting the issue on here and getting a reply, I checked and found that I had pushed the button on my light switch ass'y and turned the light off.....myself. Don't know if that is an issue on your truck, but thought I'd mention it.

i messed around with the cargo light switch if thats what your talking about it didnt change anything its really frustrating me

His doesn't have the dome override switch. Have you dissassembled the cargo/third brake light assy? Mine was screwing up and blowing the fuse, and when I pulled the assy apart, it was rotten. The dome was barely coming on and if you cupped your hands around the cargo light, you could see the bulb filaments barely glowing.
