The issue is, that AC technicians avoid going for the original vitz compressor. They goes like, ye kamiyaab nahi hai, iski koi guarantee nahi kabhi bhi band ho jaye ga. Ismai sensor ka issue hai etc. They insists more on their own kabli universal mechanical compressors with clutch plates n all.
I got my my engine replaced almost 4 months back, and bought the original compressor with it, but the technician were like these compressors won't perform well yehan garmi bhout hai etc, and I got their kabli compressor instead. Cut to 4 months now, their compressor is barely working, the clutch plate makes noise while the AC is on.
