I think this has been going on for longer than I know, but I just noticed that when my headlights are turned on, my left blinkers do not blink; they remain on. This includes the front and rear blinker, as well as the indicator behind my steering wheel.

When the headlights are turned off, the blinkers function as normal. However, the odometer flashes in synchronization with the blinkers.

I don't get it at all lol.

 

I would start by checking your grounds. A bad ground would cause all kinds odd problems.

 

I would start with checking all the rear bulbs and sockets. If you get one that melts across the terminals you can have all sorts of weird problems.
