Electrical problem
2003 Chevy Truck

The tail lights stopped functioning and when the left turn signal is on it blinks but when the brake is depressed the left signal stops and the light is out. W/o the signal on only the left brake light functions. when emergency flashers are engaged both lights flash accordingly until the brake is depressed then only the right one flashes.*******Replaced the "lighting control flasher box" that is located behind the fuse box but still have the same problem

Welcome to the forum, sorry for the late reply. I'd have to check voltage and ground circuits at the rear, when the problem occurs. Use a testlite.

Also, in the left instrument panel fuse block, there is a right turn fuse, left turn fuse, and stop fuse. Use a testlite on the fuse circuit, see if they are hot, when the problem occurs.
