:helpme:i thought this would be the best place to seek advice so here it is.. a few years ago i converted my '87 cherokee to 134a because I had to replace the high pressure line. this summer my a/c is not cooling well. I checked my pressures with my gauges and I have around 30 psi on low and 200 on high side. also the line coming out of the expansion valve is not very cold to the touch. I don't know if maybe there's moisture in the system, I put too much oil back into it when I converted or what.. when i converted i lived in a cooler climate (prescott az, and now live in tucson az), and i am aware that with 134a conversions you loose some cooling but my system is barely cooling at all.. it's not even comfortable
does anybody know the proper steps to charging this system with 134a? I guess i am going to drain down the system, drain all oil from compressor, vaccum and re-charge it.. maybe replace the expansion valve.. how much freon should I use, oil and etc? any help would really help me out.:helpme:
