Wassup to the Gang!!! I've been studying the A/C system for these cars for a while & cant get a break. So far I've changed everything listed fairly new or a year old.Using Auto Zone (San tech AC Compressor Kit LTW always comes with New Accumulator and PAG Oil) Condenser, AC/Lines, Blower Motor, Resistor, and Orifice Tube expect the Evaporator. About 2 Years I had watched someone charge & e vac the A/C system using the manifold and it was super cold then it slowly leaked as compressor would turn off and on. I then swapped out the compressor @ AZ thinking there was a problem. I know more now then I did then as well as parts, Now the issue is the compressor engages fine but tends to blow cold for a while before causing temp to rise close to the "H" Mark. Also makes it hot in car which will result into rolling down window, to let gauge keep from overheating. After a hour or so can continue with A/C into problem reoccurs. I've been using the refrigerant at Walmart for $4.88 a can I know we require 1.75 lbs of Freon 28 oz approximately 3 cans. Besides no changing the evap what seems to be the problem? I have all the tools needed to proper service A/C besides recovery tank. Harbor Freight A/C Gauge & a Vacuum Pump works fine.
