2001 Chevy Astro van windshield wipers

Chevy Astro

the windshield wipers come on when I turn my right turn signal on or the air conditioner I replaced the multi-switch did not solve the problem.

This is going to be one of those that requires tracing wires and isolating circuits. Odd that the air conditioning would have anything to do with it as the wiring isn’t close to anything. But I have seen stranger things when it comes to electronics.

No simple fix for this, just hours of tracing wires.
