Windshield wiper fluid freezing?
With temps in the 10-20 Fahrenheit range, the front windshield wipers are not working with fluid rated to -25F. The rear wiper fluid works more often, but also doesnt work sometimes.
The front fluid begins to work around 25-30F.
Anyone else experiencing this problem?

Didn't have that problem here (17 degrees here this morning). I'd question if the fluid was properly made. I'd siphon out half and try another brand, or at least add a bottle of isopropyl (rubbing) alcohol to the existing wiper fluid. Good luck

I've never diluted washer fluid and I can't say I know of anybody that does either.
Perhaps because we have such cold weather here in Canada that it isn't feasible to dilute the fluid when you are in a parking lot and freezing your fingers off.
Side note: how would I dilute my fluid with frozen water, aka ice? LOL
