Ive got a 98 gt, 88k, mostly stock. My a/c will blow cold for about 5 minutes, but then it gets warm. IF i shut it off and turn it back on, i can hear my compressor kick on, and then it shuts right back off. Everyone said I was low on refrigerant, so i bought a guage and checked. Its supposed to be at 40-45 psi, Im running close to 100. Id like to know if i can fix it myself before paying someone. My problem is amplified by the fact that the regulator in my driver door just snapped, and theres not much airflow in the car. Its almost hot enough to make me regret black car w/black leather....almost. PLEASE HELP!
