I replaced the ac compressor on my 97 buick lesabre 3800 v6 with a used compressor. upon first uuse the ac worked fine. started car about 1 hour later and the compressor clutch would not engage. next day it worked fine again. about 2 houurs later it would not work again. next day woked fine again. this same pattern happpend 3 days in a row now. Is there air in the system or a vapor lock or what is the problem?
