Hi I have a 2003 Monte Carlo ss that's overheating, fans not going to high speed help
Hi my 2003 SS is over heating, then when hot enough goes into a fast idle stage, I don't believe fans are going to high speed. They were tested with a GM tester and both activated. But my car is not telling them to speed up any ideas?? Do I need an ECM or a BCM maybe?
