Frequently Asked Questions
Why does my washer pump not work?
The most common cause is a failed washer pump motor, which is usually an inexpensive part located at the bottom of the reservoir.
Can I unclog washer nozzles myself?
Yes, a thin needle or compressed air can clear blocked nozzles. Also check for kinked or disconnected hoses.
Does low washer fluid trigger a check engine light?
No, low washer fluid typically only triggers a low fluid indicator on the dashboard, not a check engine light.
