Windhwield wipers work but no washer fluid comes out on 2001 BMW 325Ci

This was working two months ago when I had my inspection. All Fuses are juiced so not that. There is no power in the connectors to the pump. Thinking it is wiring or relays. wondering how to address and fix. Was told by the dealer it is the pump and that the cold weather can effect it, but not buying that yet. No leaks or anything like that

here's an easy test: check the voltage at the pump when
you actuate the washer stalk. if you have power, it is
a defective pump. always replace the strainer grommett
with the pump. it matters not if you believe the dealer;
he is most likely correct.
