Well when I bought the truck I was told that tanks work, switch works, didn't care cause I figured whats the fun in the restore if its not much work in the first place? Well Ive read some post and followed up but no luck. It doesn't make the sound when you try to switch it. The other post say to check the switch and a fuse! Problem is i don't know how to do either! Heres the question, How do i pull the switch to clean/troubleshoot? Where is the fuse box and which one might it be? Trucks got other wiring problems so I'm sure more than one fuse is out! Reverse lights, license plate light, dome light, cargo light, and side marker don't work! Oh one more, after i get it working can they run at the same time or do you have to switch them over manually? I ask cause interiors gonna be custom and if its just an up and down id like to put a better looking switch in its place!!!
