Hey all. just did the e-fan swap on my 04 silverado. grabbed a harness kit from www.ls1fans.com that uses two trigger wires, blue 42 and green 33 for high and low speed fans. the fans work both high and low for the engine, however if the truck is cold and i turn the a/c on, the single fan will not come on. i'm sure it is something on my end for the tuning, if anyone can see anything i'm missing i'd be grateful. thanks in advance.
