I would guess that Buick uses electric heat for the washer fluid. If they used the coolant, you would have to wait for the engine to warm up before you could de-ice your windshield.

I believe you are correct. I saw under the hood of a Lucerne CXS yesterday (Monday) with the 4.0L northstar V8. From what I could tell, it appeared that the resevoir was wrapped in some sort of blanket/insulation material, which probably had a heating element in it. I didn't have much chance to investigate that thoroughly, though.
