cigarette lighter wiring

Car is ´67 Barracuda and seems that my cigarette lighter blows the fuse all the time and having short circuit somewhere. Can I just unplug the lighter wire and leave it unplugged? When I unplugged the wire the fuse did not blow anymore.

I´ve problems also with the left stop/signal light and back up lights so could these be related to the cigarette lighter problem?

Thanks in advance.
