I keep blowing turn signal fuses! HELP!

1990 B2, I even thought it was something with the switch, but I swaped that out and I still keep poping that 15amp fuse for the turn signals. Any idea what I should check next? Thanks!

Does fuse blow with key off?
Does fuse blow only when one side is selected? i.e. left or right turn signals

Instead of a fuse I would use a 12v test light in place of the fuse, it will be bright because of the short and then get dim or go out when you find it and lift it.

here is a wiring diagram:

One thing to check is a trailer connection, even if you never used it, these do get corroded and will short out the system.

I will try and test it out today, thanks for the help.

Okay, just got into this again...

The turn signals work if I have the key in run, but once I start it up they pop. I checked out the wireing diagram but I am not very good at reading that kind of stuff, so... From what I gathered I should next check

1) trailer lights (not sure if I have any?)
2)turn signal flasher - could this go bad and cause the fuses to pop?

Anything else I am overlooking? Thanks.

A blown fuse in 99% of the cases, is a short. Meaning, there is a place where bare wire is touching something it shouldn't be touching, thus allowing more electricity to flow than the fuse allows. Hence, blown fuse.

Do you think it would be between the fuse box and steering wheel? Or by each light?
