It's been a busy fall, and I haven't yet cleared enough space in the garage to get my truck inside (it's my only "chore" on the list for tomorrow). We've had some early-season snow in Detroit, and every morning that I've had to drive into work after it snowed a little, my windshield washer won't spray. I usually clear most of the snow off the cowl, and I've never owned a vehicle that can't "power through" a few flakes at the base of the windshield. Anyone else having issues with this?

Did you refill with winter washer fluid? Lines froze up?

 

The windshield wash solution doesn't have the necessary anti-freeze mixture. The entire system needs to be thawed-out and flushed with the correct windshield wash mixture.

BTW .....

HINT/TIP: Put your vehicle information (year, model, cab, trim, engine, wheelbase, _x4 drive, mileage, etc., etc., etc.) in your signature -OR- provide it in your posting(s).

Very well known issue on the 2015 up trucks:

Simple solution? Remove check valve, carefully drill a 1/16" hole into each of the 3 holes and never have another issues with no fluid when its cold.

 

The stuff I've been using since the first time I had to refill it is a winter blend that freezes at -25F, so I don't actually think the washer solution is freezing. It seems more likely that the snow is melting into the nozzles and blocking the spray at that point. I've just never owned a car that collects so much in the nozzles... to the point that it can't melt its way through in a few seconds.

Truck info added as well.

 

After reading a few of the "suggested posts", this sounds like the most-likely culprit. Thanks. I'm gonna look into removing these check valves.

 

No problem and mine never freeze after drilling out the valve.
