2006 cooling fans
2006 GMC 5.3
all stock truck OE dual electric fans I noticed today the fans do not turn on unless the a/c is turned on. And they blow somewhat slow it seems. The truck has never overheated but I am curious why the fans don't come on with the a/c off. With it fully warmed it runs at 210*. I am wondering how are these fans setup? Primary and secondary fans? Single or two speeds? How does one go about testing the fans and switches on this 2006? In comparison my 2009 Yukon's fans blow like crazy.
