    Got a problem with the named vehicle. Left rear turn/brake light doesn't work. Right rear flashes really fast. No emergency flashers. I was told to look for a bad/loose ground. Does anyone have a diagram of where to look for the grounds on this circuit? Thanks a bunch in advance

    go to like autozone or one of the auto places by you they should have a chilton manual and they should also have the haynes manual i forget which one but they put a decent wire scheme in em so take a look at both

    The usual suspect is the flasher itself or the bulb sockets. My guess would be rear socket failure.

    Found the problem to be a add on "T" between the main harness and the crossover. The "T" is for trailer hookup. Removed the T and plugged the connectors together and viola! Got lights that work.
