Very dangerous problem as I couldn't see the road on I70 in Colorado mountains as the temperature dropped to below 20 degrees. Had to pull off onto the shoulder and wait until heat from engine thawed the squirt nozzles. Happened three times on the trip. Mag cloride really smears windshields. My washer fluid is rated for -20. I see quite a few identical issues listed, wonder what Ford has to say about this problem?
