after trying to roll down, the window stopped as a rapid clicking sound heard.

Not sure if it's too late to answer, but many times all you need to do is clean out the window channels and then lubricate them with silicone paste, or silicone spray if the paste is too hard to find. The paste works better, but you may have to order it online. If that doesn't fix it, then you will need a window regulator. And maybe also a motor. You can find an assembly of both together in aftermarket, that should work fine. OEM ones are very expensive.
