I hope you know where is the fuse box in mehran? open the fuse cover and on the very first left side, there is ignition fuse. You can only take a guide under the fuse box, as it has the fuse location diagram on it. check if its loose or tight, or remove the fuse and see that area is it ok or it little bit melt. check your fuse and its ampere number as well. I guess it needs to be 20ampere. not sure but again you can see at the diagram under fuse box cover.
Not sure, if that can be the reason but, we never know..
Make sure you dont messup with any other thing and fuse box location is under the dashbaord on right side, behind the bonet opener.
