Hi @ehmaad
Hope you are fine.
Its really sad to hear this you are suffering the same problem that i am facing from last season. But i didn't downgrade the system or try some other model AC System. I wouldn't recommend to do this.
I would say try to find original kabli sensor wala compressor come in gli in good condition and flush the whole system properly and try this as well. Here in Toyota Islamabad have AC MACHINE imported from ITLAY that has whole system of charging accurately according to spec, flushing whole system , vacuum and other high end diagnostic system. In other words, that machine have all in one for AC.
But finding a good compressor is challenging now a days. I have seen many corolla owners have downgraded the ac compressor to clutch one but they have load and pretty less cooling.
