Have a 2000 es300 and replaced the battery and now the cooling fans start and run all the time. What could be happening at this point?

THE COOLING FAN RELAY MAY BE "STUCK" INSIDE
IF YOU "THUMP IT", IT MAY COME LOOSE, AND THE FANS STOP RUNNING
REPLACE IT, IT WON'T GET BETTER

Tried the cooling fan relays and the cooling fan sensor and the fans still run all the time even after engine is fully warmed up. Will the next step be to go to the dealership and have them put it on a computer? Thanks David
