I'm out of ideas. Dash lights keep blowing ccc illumination fuse #35 in fuse box. tryed diconnecting all interior lights, and checked all wires comming off of the light switch. Any ideas would help.

 

do you have a aftermarket radio? some people make the mistake of hooking up the illumination instead of the dimmer wire on the radio side of the harness.

 

Ok, I figured this out. I will let you in on the problem. On the newer trucks, that have the TIPM under the hood. Thats the intergrated fuse box. All of your interior lights and dash lights are controlled through the instrument cluster. So now mine has a short in it, I'm glad it's still under warranty.
