My left corner light does not work. Its brand new, nothing wrong with the fuse or bulb. So it must be in the wiring because sometimes it works, sometimes it don't. Don't know why, some help would be great. Thanks

Put another new bulb in it. Trace the ground wire from it and make sure the contact is clean. Otherwise, you're in for a fun time hunting down the problem, there's no magic way to figure it out. It's probably either the bulb or ground wire though, unless you've damaged the wiring harness somehow.

i had the same problem,but i had to get a state saftey check i just cut the power wire and ran it to the low beamplug on the head light next to it works great no problem.

check the ground wire.
