My cooling fans have serious issues.when my car (88 IROC Convert. 5.0) fans come on they wont turn off. I know everybody is saying "stuck relay". That aint it. When the car is cold the fans dont come on. After running for about 15 minutes ther fans come on and never turn off. I unplugged the fan switch in the head,the coolant temp sensor, the pressure switch on ac line, turn ac controls to off in car and the damn fans still run.I have a scan tool and the computer is not calling for fans.I am thinking the computer is the problem.. Please someone HELP!!!!!!!!!!!!!!!
