1997 Chevy k2500 6.5 turbo diesel extended cab long box
hello, i'm new here so just hoping for some assistance. having problem with my radio and speaker wiring. all of my speakers work except the drivers front door speaker. if i test the wires with a test light i get power through all wires including the negative speaker wires for all speaker locations. but no sound out of drivers door speaker. i don't understand why i am getting power through the negative wires. i even switched the left and right speaker wires and still no sound out left door. this is on a 1997 k2500 extended cab. any help would be greatly appreciated.
