yes i have 2 twisted pair of wires, (yellow/black,Yellow/green) and (grey/white,grey/black) I do NOT have a solid yellow wire anywhere. I tapped into the yellow/green wire and my amp stays on all the time.
thought i would shed some light...
summer is gonna be upon us soon and guess what no ac and i'm in the south!!!
researched problem and i found this thread. Gm dealer gave me parts at wholesale price so i decided since i am in there might as well replace KNOWN ISSUES.. so i replaced....
1) condenser
2) high pressure line from compressor to condenser
3) installed updated bracket
4) two band aids later
5) pulled a vacuum and it held (fingers crossed)
not a hard job just be ready to cuss the 3 bolts on the cross member (each side) that are on the bottom
(note video is same for a 2014)
