Anybody can guide me how to repair my AC switch as figure above? I got renault clio 2006 1.4 16 valve sedan petrol. When switching to 1 not work, 2 not work, and 3 not work but 4 it works perfectly. Does this problem from the switch itself or is there any juction box or control box for it that i can repair. If there is does anyone guide me where this located? thank you so much in advance...
