Common Toyota Windshield Washer Reservoir Problems
The Toyota windshield washer reservoir is responsible for storing the fluid that cleans your car's windshield. Without it, the entire windshield washing system will not be functional as it needs water to be able to clean. In case your windshield washer reservoir becomes a problem, learn how to fix it with these easy-to-follow tips.
The water in the windshield washer reservoir is frozen
Have you ever pressed the washer button on one cold day and you find that there is no water squirting out of the nozzle? You then checked if the nozzle is clogged or if the tubing is disconnected. However, when you opened the windshield washer reservoir, you discovered that the water inside is completely frozen. What must have happened?
First of all, remember that what you put in there was plain old H2O, which is susceptible to freezing especially during winter. While you will now have to go through the inconvenience of even replacing the reservoir, you should also learn why it's necessary to use the right washer fluid. This liquid that you can find in many auto parts stores has high alcohol content and therefore will not freeze. It's okay if you use water in other seasons, but you have to drain the reservoir before winter and refill it with washer fluid.
The windshield washer reservoir is cracked
If you have been filling the windshield washer reservoir with water and the liquid inside froze during the winter, then this could be the culprit. After learning your lesson of not using water as your windshield washer, you should also learn how to fix a cracked reservoir. One way is to have the component welded with conventional plastic-welding techniques. Do not use a silicone sealant as it does not have the adhesive properties or the strength to hold the windshield washer reservoir together. However, if you want to fix the component yourself, buy a strong plastic tank repair kit from local auto parts stores. Then, take out the damaged component and follow the instructions included in the package to seal the crack.
Other troubleshooting tips
While you have the windshield washer reservoir open, check it for dirt as well. If the grime has sunk to the bottom of the component, take out the reservoir from your car and clean it thoroughly.
Aside from the reservoir itself, it is also best to inspect the pump operation. Follow the washer tubing from the windshield washer reservoir until you reach the end. Then, disconnect the tube and have an assistant press the washer button. If there is a strong stream of washer fluid coming out of it, then this indicates that the pump is still good.
