Hi looking for some help regarding cigarette lighter sockets. When i bought the car the 1 beside usb was not working so i used the rear near passenger footwell centre section and that went off aswel now. The fuse is ok i checked its in the engine compartment its a 20amp and i also switched it with another 20amp and both fuses are fine. What could it be? Will i need to replace both cigarette lighters if yes which 1s should i get. Any help will be appreciated thanx.
