2022 Edge Titanium, 35k miles, purchased 6 weeks ago.
-Front & rear washers were working when above freezing
-During +5 degrees F, 300 mile trip home with dry snow, neither front nor back worked. Wipers came on for a few swipes but only rear fluid "oozed", not sprayed, then it stopped also. I purchased some -20 degree blue fluid and when adding it noticed coating of ice in filler neck. Blue fluid went through the thin ice in the neck but only could hold a few ounces. Assumed someone had filled it with water. With the cold temp and dry snow it wasn't a big problem on the trip.
-Front washers thawed overnight in garage. Emptied the tank and refilled. Rear still frozen a few days later, It's not thawed near the garage door.
-I've just noticed when trying rear washers I can't hear the pump. I should be hearing the pump even if there's no fluid due to frozen water still in the rear line?
-Any thoughts? I'm a newbie here, this is my first post. Looking forward to years of shared advice.
