2002 Elantra WIRING issue

ok where do i begin....
Customer drives the car to work just fine and dandy.

goes to leave work and everything is dead NO POWER AT ALL!

We get it towed to my shop and the first thing i do is put the battery on the charger and instently the Cooling fans kick on.

First thought in my head is the relay so we changed the relay and it still runs all the time.

So since the coolant temp sensor tells the fans to kick on that was the next part we changed with still the same outcome.

Soo we started looking at the wiring and i cant find any breaks or cracks in anything and its never been wrecked in the front end so i have no idea where to look next.

Has anyone had this problem before and if so what was the issue with yours?

Any ideas are better then no ideas and thank you in advance!

I found a wireing diagarm this morning and there are 3 relays that fun the fans and now its fixed

thanks guys
