electronic problem

[geoff thomas]

The lights on the top of my cab all have bulbs in and when you flip the switch to turn them on the led on the switch lights up but the lights on the cab dont come on, they have never worked since i got the truck any ideas?

Sounds like they were added after the fact. Your gonna have to trace the wires from the switch and see what is going on. Make sure you have power and ground there first which you should since the light is coming on...

yeah there is power and ground should i possibly be looking for a fuse? in the main fuse box? or are they wired in series through the roof so if 1 bulb is gone nothing works like a christmas tree???

If the fuse was blown you wouldn't have power anywhere.

I'm not sure about the wiring being in series. Never thought about that before....

Take the lens cap off of the lights and check for power and ground at all of those and that will tell you..

LOL. They should come on when your parking lights come on. If your parking lights are on then I would pull the covers off the cab lights and check for power and ground at each of those.

Your parking lights are the orange colored lights in the front. They come on with the first click of the light switch and also stay on when the headlights are on. The first click turns all parking lights on and the second click turns headlights and parking lights on. Does that help?

so your parking lights are not coming on??? If so you need to check fuses. Look in the owners manual and see which one is for the parking lights...
