There were two styles of pulse wiper relay, I call them the "old" and the "new". The old was larger, aluminum case relay, and the new is the smaller, plastic case relay currently sold by all the parts places. They function identically, but mount into different sockets. If your car is a '78, you will undoubtedly use the "old" style.

This is normal. The clicking is the electronic relay engaging and disengaging.

Your problem is most likely in the wiper switch, motor or wiring, as the pulse wiper relay is only involved in the intermittent function and the "wipe after wash" function.
