Why won't my compressor come on when trying to charge my air conditioner?

What is your question?

2001 Buick Park avenue ultra - 135000 mi . Also ac charging gauge indicates my system is showing to be overcharged, but it worked great the previous summer so I can't figure what maybe failed?

What makes this problem better or worse?

Na

How long has your 2001 Buick Park Avenue had this problem?
