Hey guys,
short story, 5.3 in s10 blazer, ls1 e-fans, wired up like camaro, low speed = series, high speed = parallel. Works great w/ temps I've programmed.
Just added a/c and I cannot figure out how to get the fans to turn on with a/c. Not sure if I'm missing a setting in hp tuners or what.
The ECM came out of an 02 Yukon, red/blue connectors. I know the 02 model didn't have e-fan option.
Can I get the ecm to control the fans w/ ac or am I going to have to tap the a/c request line to get the fans to run w/ ac?
Thanks!
