Hey Inder, wondering how you sorted this problem? If i am in your place i will also doubt the fuse junction box to thoroughly check for some burnt fuse that must be doing the brake light directly.

This could be due to one of two reason:

-->Wiper motor died

-->Wiper motore fuse or relay died.

Go to Satwa, near big mosque there are few car fixing (small time) shops are there of many bengali boys, they are ok (not so good) in initial checkup. Get it checked for failing fuese or relay all you know with such a small issue you can get your problem sorted. If they advise that wiper motor is busted, then changing it is the only resort, im afraid. That might be little pricey.

i have found a burnt out of radiator hose or i think some wire. what exactly i dont know but how do i know what is burnt its rubber made.
