I have a 98 Suburban 4x4 and was checking over the A/C system because it isn't blowing very cold. I know it needs charged, but I was wondering if anyone knows what the pressure is suppose to be in the system? Anyone have a manual that tells you what it is suppose to be? It seems kind of high and want to make sure all is well with it before I get it charged up. Thanks

 

You say you are going to "get it charged up". Does that mean you will take it to a shop and let someone else do the work? If so, the mechanic at the shop should know what's proper for your system. If you need a recommendation of someone knowledgeable and reliable, say where you are located and maybe someone here will know someone.
