I have a 2013 supercharged that I believe has the windshield washer system is frozen...dang minus degree weather. I think it must have had water in it before I filled (only a cup or two) of -20 deg fluid. How had is it to get to the holding tank, motor, etc? I don't have a heated garage and can't wait until warm weather...April in Michigan???

 

Run the car for at least 30 minutes, the engine temperature may warm it up a bit, use your washer to pump out the melted water, then add more antifreeze washer fluid, it will continue to dilute and hopefully the mix will then finally get to a level of antifreeze which it won't freeze again. I had to go through that with my son's Jeep as he lives in Florida and they filled it up with washer fluid without any antifreeze and he drove up here and it froze completely. Luckily the tank didn't not burst. Good luck!
