Your windshield washer stops helping in freezing weather. What is the most likely preventable cause and fix?
- A.The wipers are too new
- B.The reservoir was filled with summer fluid or plain water; refill with winter-rated washer fluid and clear the nozzles
- C.Add engine coolant to the washer tank
- D.Washer fluid type never matters
Correct answer
B. The reservoir was filled with summer fluid or plain water; refill with winter-rated washer fluid and clear the nozzles
Why
Summer washer fluid can freeze in the lines and nozzles just when road spray is dirtiest. Winter-rated fluid, good blades, and a working defroster together keep the windshield usable in storm traffic.
