bro that i dont know exactly myself,i got it installed from mughal car ac in rwp,and the owner is relative of my very near and dear one,in broader vision wat i understood that it shouldnt be chinese and much of price difference is there in quality of gas,where as my bro in law installed from 3S suzuki in same price u mentioned and after 3 months some noice started coming from the vehicle when the ac was switched on which was due to fault of pully installed for ac belt,when i got ac fitted in mehran my vehicle dashboard wasnt opened that much as i could see in the snaps above,they just have to fit in a button with connection of wire,for that purpose driver side all metres and dash board need not to be opened that much,plus for fitting of inner unita good fitter will do it without opening the second seater dash board side as well
