1998 a/c performance
 

im working a a 1998 deVille, installed new a/c compressor after i recharged the system the lowest temperature out of vents 60 degrees, i have under charged and over chaged by half lb. still no change i think compressor cycles too fast does any body have any idea on what is causing this????

Pull the codes up on the dic and it will tell you what is going on. if it cycles on & off it still may be low.
