I am having trouble figuring out why the "Check A/C" light is on in the dash. I installed the new A/C kit, pulled a good vacuum, and charged the system, but I can't keep the light off long enough for the A/C to properly charge. I hear a popping noise in the dash, like a blend door motor in an old chevy pick-up, and i was wandering if this could be why the light keeps coming back? Does anyone have any tips?
