The low washer fluid light on my Chevy Silverado was constantly on, and after some research, I determined the likely culprit was a faulty level sensor. I replaced it with this genuine GM product, and the issue was resolved immediately. It’s a reliable replacement part that fits perfectly and works as expected. Highly recommend for anyone facing a similar problem.

This worked perfectly for our 2013 Tahoe LT Z71 model. Cleared the “low windshield washer fluid” message, right away! All parts included worked perfectly and it’s a genuine AC Delco part. Not that terribly hard to change too. Took me less than an hour.
