Ek time pe every ac wala was putting 2002/2008 Corolla in every car.
Now they love terious/Duet wala compressor. Probably jahan ziada bachat.
I also have Duet wala in my 1.8, extremely against alteration have replaced bracket twice just to save costs.
Now the orignal one (Used) costs around 18k for compressor only. If change compressor coil and condesnsor would be changed aswell costing 35/40k roughly.
Some dumbas cooling or AC throw is very bad with the ac filter installed, I have removed my cars AC filter. Still cooling at the back isn't great. (Although cools well but the fan throw is still low)
