A/C temp - what is yours?

[MJB_Hummer]

Is your clutch staying engaged or is it cycling when the AC is on?
Mine was cycling and I was only getting warm air. Charging the refrigerant did not help.
I found a service bulletin from ACDelco with regards to AC blowing warm air: http://www.acdelcotechconnect.com/pd...sb_03D-128.pdf

Per this bulletin, replaced the A/C Low Pressure Cycling Switch and now my air is back to ICE cold! The switch is only $22 dollars at your local auto parts store, so worth a try! Only takes a few minutes to swap out.
