Its been a mystery to me for years now.

Whenever i use the rear windshield wiper fluid my front wipers come on, and vice versa..is this the same with you guys?

p.s. I think my wwf pump is busted now since It doesn't squirt anymore. (reservoir full)

My front and rear wiper work independently, maybe there's some funky wiring short in there. You should have someone listen and try to hear the pump whine when the engine is off, it could just be a plugged line. I've had the front nozzles freeze up on me on the highway in cold weather, but somehow I don't think you have that issue.

i had the same problem ez fix, i noticed mine did this after i got mine back from the body shop, there should be 2 hoses from the pump switch them and you will be good id would take a pic but my car is about 15 min away in a storage unit.

It could possibly be a blown fuse too, I'll have to check that out soon.

It just makes no sense to me, if I use the front washer fluid why does the auto wiper start going off in the rear.

i wish i had my car to test it out on but maybe there are separate plugs for each pump that are the same style and they got switched?

Possibly, whatever it is it needs to be reversed, it annoys the heck outta me
