Just the other day, well, night, I noticed the lights in my dashboard were out, as were all of the lights for the radio and environmental controls. I checked the fuse for this (F7) but it wasn't blown, however, I did discover that F3 (15A) was blown. I replaced it and the IP lights came back on, but now the fuse burns out after I turn on the headlights!
Seems like I have a short somewhere. Any ideas?
Also, if anybody has it, I'd like to see a wiring diagram, including one for the main headlight switch (i.e. a pinout diagram), which I've managed to remove and would like to check.
And before you ask, No, I didn't recently install or do anything to the truck.
Thanks in advance,
P.S. I have a 3.0L V6 w/ manual transmission. No add-ons that I'm aware of other than a 3rd party anti-theft system. (It was already installed when I bought the truck 4 years ago. I don't know much about it other than it says "Pro Lock" and they're out of business now.)
