Hi Milind,
First of all you would need to check the power supply to the switch. Check the fuses to see if any is blown. Sometimes designated fuse are good but there are other supporting fuses that can affect the system so it is best to check all fuses.
Such problems could be due to a bad switch, blown fuse, or a connection somewhere is broken.
