Queda bien, sobre el empaque del sensor original. Ya no me aparece el mensaje de falta de líquido

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 product is a genuine AC Delco replacement part. It was an exact fit for my 2011 GMC Sierra. Simply swapped it out with the old sensor. I no longer have the 'low washer fluid' prompt on my dash when the washer fluid reservoir is full. Probably should have bought this a year ago.

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.
