The wiring diagram shows if you have the 4 speaker system there is no external amp, but if you have the 7 speaker system, (3 speakers across the dash), you will have an external amp, located behind the glove box.



Yes, i have the 7 speaker system. So the only way to find out if it is the amp is to buy another used one, correct??



Well, you could unplug one speaker at a time and see if it starts playing again.

Has any work been done on the truck that could have caused a wire to be pinched, chafed or something like that? Might not show up right away.
