Find and Fix: A Toyota Corolla Windshield Washer Reservoir Troubleshooting Guide
Are you experiencing less visibility on the road? Can't see through the dirt specks and bird droppings splattered on your windshield? Fortunately, a few squirts of washer fluid can help remove those nasty marks and make your windshield spotlessly clean again. To ensure you won't encounter any problems each time you activate the windshield washer spray, you should always check the condition of the reservoir. This plastic tank is where all that blue fluid comes from, so you'll experience little to no spray when it gets damaged. If you think your Toyota Corolla windshield washer reservoir is no longer holding the washer fluid properly, better roll up your sleeves and do some troubleshooting right away. Here's a guide to help you find and fix some washer reservoir problems:
Lack of washer fluid
If the nozzle won't spray out washer fluid, you probably have a cracked or leaking washer reservoir. Tiny cracks usually appear on the reservoir over time as the plastic material becomes brittle and vulnerable to damaging elements. Minor or high-impact collisions near the wheel well where the washer reservoir is located may also break or crack the plastic. Do a quick visual inspection on the reservoir before attempting to repair it. In some cases, the problem may not lie in the reservoir, but in the parts connected to it, such as the nozzle, grommet, hose, and pump. A clogged nozzle, a damaged grommet, a leaking hose, and a defective pump may also prevent the washer fluid from getting out of the reservoir. Check these parts for damage and replace them if necessary. To repair the leaking reservoir, you may apply epoxy over the cracks. If this doesn't do the trick, get a replacement immediately.
Knocking and clunking sounds
If you hear unusual knocking and clunking noises from the engine compartment when going over bumps, it's most likely a loose windshield washer reservoir. The sound it produces is different from a loose metal part; it's more like plastic knocking against the engine compartment. To fix this problem, tighten loose screws and replace missing bolts or damaged seals if necessary. This would help keep your washer reservoir attached to the assembly for a longer period of time.
