Yep, my stealership topped off my washer fluid last week. Pulled the stalk for the first time this morning (below zero temps). My headlight washers came on but nothing on the windshield. Got out of the car to check and my headlights had frozen goo on them and I'm pretty sure my wind shield washer line is frozen as well
Now I'm thinking if the washer fluid used by my SA had any anti-freeze in it. Should've checked while he was filling it up.
