I was trying to figure out what is wrong with my 4 wheel drive I took the switch on the fly switch out and and for some reason thought that I could just cross the connection. When I did that I must have ground it out because. I heard a popping sound and my dome light went out and I lost the use of my power windows and wipers. And also when I shut the truck off the radio will come back on.

Unfortunately, I suspect you either damaged the module or just popped a fuse.

Basically, the power feed for the switch to the module is a shared splice through the multifunction switch. So, we need to go to this and check fuse 11 and find out if that is blown. If it is then we need to replace it and you should be fine.

Then we need to move onto the interior lighting system.

However, I attached the wiring diagram below that will help with this.

Please run through this and let me know what questions you have on this.

Thanks
