The clutch bearing failed and we replace the whole unit compressor and clutch. (rebuilt) when we charged it with R12 compressor seized up after about 3 1/2 cans long before full charge. Then we returned that compressor got another rebuilt and converted to R134. That compressor also failed before full charge. We are following the instruction on the compressor to add oil before charging. Again we returned the compressor and this time we took the Suburban to Brake Masters and they tried to charge it with the same results. We then bought a new (not rebuilt) compressor and had the same results twice. We can not figure why the compressors are seizing up. We also replaced the accumulator dryer and the orifice tube. Old orifice tube was not plugged. Is there something we are missing that is causing this to continue. Please help it is climbing to 100 degrees today!
