Keep popping turn signal fuse

[Boston GN]

I've popped this fuse (20amp) two times within the last weeks. I have no idea where to begin looking for what could cause this issue. Any ideas on where to begin? I've never had this issue before with 18+ years of owning the car.

Check the operation of the turn signals on ALL bulbs both sides.

Any bulbs not alternating and flashing properly need fixing.

Same for the back up lamps as this fuse runs those as well, both sides.

Most likely an intermittent short but all bulbs and proper operation need checking first.

^^^^ THIS.

If all is good, there is a ground wire that screws to the left rear tire well that can become corroded where it attaches. It grounds all the rear lights.
