With the winter months almost over you may have completely forgotten that your windshield washer fluid froze this winter. If the temperature stays cold in your area of the country it may have stayed frozen for months this time. Even if you live in a warmer climate, usually once a frozen reservoir thaws it won’t work quite right.
If your windshield washer fluid is frozen, or has frozen over the winter, it is important to check the integrity of your windshield washing system to make sure it is operating properly. Just like a full water bottle to freeze can rupture the water bottle, allowing your windshield washing system to freeze can rupture the fluid reservoir, damage the pump, split the lines or damage the nozzles. These damaged components can prevent your system from working properly and can end up causing other problems as well.
Start by checking your windshield washer fluid reservoir for cracks or leaks. Sometimes the easiest way to do this is by adding new windshield washer fluid slowly and checking for drips. If your windshield washer fluid reservoir is in an area where it is difficult to check for leaks, at least make sure there is a clear path to the ground by checking for any plastic shielding under the reservoir so you can spot leaks quickly.
If you find a leak, your only option is to replace your windshield washer fluid reservoir. If you get the reservoir filled up all the way without any leaks, you can move on to inspecting the rest of the system. This is most easily done with a partner. Have your helper jump in the driver’s seat and turn the key to the “on” position without starting the car. Then, have them engage the windshield washers in short bursts. This will allow you to listen for the windshield washer fluid pump running. In most cases, if your windshield washer fluid pump has frozen the damage will be catastrophic so if the pump motor is still running then most likely the pump is functioning properly. Similarly, if your windshield washer pump isn’t running, your only option is to replace the pump.
Lastly, you can check the lines that carry the washer fluid from the pump to the outlet nozzles on your hood or your wipers. Much of these lines can be hidden under fenders or other equipment and even if you can find them often cracks or holes can hide in the rubber so the best method for discovering a leak can be simply running the washer fluid pump for an extended time and watching for drips. Have your partner engage your windshield washer system for 15-30 seconds and watch around the reservoir, in the engine bay, and around your windshield wipers. If you don’t immediately see any leaks you can also use this time to check for proper spray pattern from your windshield wiper nozzles. The nozzles should evenly spray windshield washer fluid onto your windshield in the areas that your wipers cover. If you find a leaking section of hose, simply cut out the broken section and replace it with the same size hose. Washer fluid hose sections and connectors are easily available at your local auto parts stores.
