Isuzu Repair: 1992 isuzu amigo, isuzu amigo, lamp assembly

Question
my left turn and back up lights are not working, but the stop light, 4 way flasher and running lamp do, what could be the issue?

Answer
Hello, Jason. Well your problem could be a bad bulb, or fuse. Also check for any loose connections or loose grounds on the lamp assembly. Sometimes the circuit board on the lamp assembly goes bad, but I would go from simple to complex first. If you have any more qestions I am here.
