Are you facing start up issues or have a certain electronic part which is non functional? Well this could mean that your car has encountered a blown fuse. Many of the cars sold in the Indian market have either one or two separate fuse boxes, one which is located within the cabin right above the knee of the driver and the other in the engine bay area.

For a lay man, this does sound like a tedious task but rest assured it is a relatively simple thing to fix. Having located the box, open the plastic cover and instantly one can find a number of coloured fuses placed very nicely within the compartment. Turn its top cover upside down and automatically you will notice a graphical representation indicating towards different fuses and their respective utility in your vehicle. Normally, the manufacturer provides for a couple of extra fuses that could be used to fix the problems but just in case there aren’t any then you could perhaps go to a nearby mechanic to procure the defective piece at a very nominal price.
