Hi my first post, i have a 2014 Kw t660 my Cab ac blower stop works and y decided fixed by myself, based on my experience (not much on “newer” trucks) I go check fuses and relays still good but I replace the fuse anyway. Then I unplugged the fan harness and I got power and ground so I supuse that I need a new blower (my first mistake) I expend $414.00, when I replaced the problem still, my surprise on that kind of blower they come with a resistor so there ir a third wire on the plug, so I check the wire and nothing coming from before plugged but when is plugged the third wire come on power so I put a straight ground on it and the blower comes on but just for 2 seconds and then shut off, so my conclusion was that I need a lower ground that doesn’t come from the controllers so y decided buy the controllers (second mistake) spend $730.00 and when I replaced the problem still. Now I try almost everything. So I was thinking that I has a lost ground or power before the controllers because nothing comes out for the wire that goes from the controller trough the blower motor. Please anybody can help me!? Thank you God bless you.
