I have a 2001 Ram 2500 with the Cummins. I recently had my rear brake
lights and turn signals go out on it. I have turn signlas up front,
the 3rd brake light works fine, the fuses are all good in the fuse box
and the PDC, and the brake lights and turn signals work fine on my
trailer harness plug in, oh and the bulbs are good but there is no
power at the bulb sockets for either the brake light or turn
signal...however there are running lights...any ideas what else to
check?
