I have 2005 chevy silverado 1500 z-71 have problem with cooling fans coming on when truck is cold and staying on until the battery dies. i've changed the cooling sensor and swapped relays, I've also had mechanic put scan tool on truck and said it was between computer and relays. any ideas.
Check your heater core if there is no circulation probally pluged sometimes you can flush the cooling system to solve your problem
