Simple fix turning into nightmare/fishing a wire ideas

OP here...

GOT IT !!!

Thanks for all the help.

Must of had 3 hours total trying different things. Finally got it by...



Found brake light wire from the inside. Pulled wire rest of way inside.

Clamped wire with those forceps that have locking notches on them.

Put wire back in and took coat hanger from outside and had wife giving directions to hook hole in forceps.

Glad I learned on the side I did, even though it was a mess, the other side is the shower with no access behind it without pulling it out.

Thanks again
