My lights are all jacked up. I can turn on the headlights from the switch but i can't turn them off unless I lock the truck and i used to be able to from the switch. Also my interior lights to work and my tail lights and license plate lights don't work eaither. I've replaced the switch and tht didn't help. Any ideas???

 

First check your fuse, make double sure fuses are good. If you have DRL it could be the module/bad diode. Check that your body grounds are clean and tight. Make sure your fuse box isn't damaged. Gem module can do some strange things if it gets wet, corroded. check out http://www.fordf150.net/forums/viewtopic.php?t=54051 some good info.

 

Where can I find all that

 

Look behind your driver kick plate. I don't know your model, year, or motor. It could be you have a window seal leak down onto the area. It's fairly common with this type of problem. You probably have to disconnect battery, and unplug from box to see behind it, and inspect for corrosion, water damage of components if you suspect, see blue green stuff or rust. Probably if you have damage, once you touch it it's done and you will need to make a trip to a parts yard for parts. This stuff costs $$$ new.

 

Driver kick plate? Is that where the petals are

 

look at your manual for help, kick plate is along side your left foot.

 

Ok
