Does not always play well with others
OK,1998 K1500 Suburban,5.7 4L60E. The truck came with the A/C system inop. I finally got around to repairing it. I have replaced the following due to the fact that the system was open when I bought the truck, drier, condenser, orifice tube, compressor ,high pressure switch and the hose assemblies.Also all new "o" rings that were lubed with Pag oil. The evaporater core in the dash was flushed twice.
I vacuumed the system down for 1 hour and it held vacuum over night,8-9 hours.The system has 8 oz. of PAG 150 as per the compressor manufacturer specs. I have 36 oz of R-134a in the system(as per manufacturer) The compressor runs for 10-15 seconds and cycles out and repeats. Any help would be appreciated(I am not an A/C guy)
