I have just recently purchased a 2007 Chrysler Sebring and I think it may be the best car I have ever purchased!! I am having some issues trying to locate the low service port so I can check and top off my 134a. Can anyone give me any direction on where this is located? Also, does anyone know how much pressure there should be? I keep seeing numbers from 30lbs-55lbs of pressure at maxiumum. I would appreciate any information. Thanks.
