Hello guys, I just bought a naija used 2010 Corolla with bad ac. Took d ac for fixing, d tech. Advice we flush d system due to d fact dat d compressor is bad and d system showing signs of black colouration, I bought a used compressor 22 manual, he flused d condenser since it was still new and change d condenser filter, removed d valve and flushed d whole system using cooking gas according to him, and recharge d system.
But d cooling was not effective except wen I'm driving, he advice I drive and observe, within a week no changes as per cooling, so wen I pressed d H valve with d car key I saw very black gas/ oil coming out. Please what do you advice I do, d tech. Said d compressor is having low pumping hence need to be changed.
I urgently need advice on wat to do next. And I will be going back to d tech. Dis morning.
