Sometimes my left blinker doesn't work..its random. Anyone have a clue whats going on? Maybe just a loose wire?

 

Check your wiring route, make sure that there arent any tears etc. Once you've done that, check your connections, they may have become loose, then take out the socket, take the bulb out, get a screw driver and scrape those two prongs down at the bottom of the socket. Sometimes they become corroded.
