GMC Sierra 1500 Glass and Wipers Warning Signs You Should Not Ignore

Most glass and wipers problems announce themselves well before they strand anybody. On a 2014-2018 Sierra 1500, these are the ones worth acting on.

1. Chattering or streaking that returns within a week of new blades

It rarely gets better on its own, and it usually gets louder before it gets expensive. Start by looking at wiper blades.

2. A rain sensing system that triggers late or not at all

This one is usually early, which is good news, because it is cheap to fix early. Start by looking at wiper motors.

3. A washer pump you can hear running with nothing coming out

This one is usually early, which is good news, because it is cheap to fix early. Start by looking at wiper transmissions.

4. Wipers that park in the wrong position

It rarely gets better on its own, and it usually gets louder before it gets expensive. Start by looking at wiper blades.

What to Do Next

Blades every six to twelve months. In North Texas, summer heat kills blades faster than winter does.

Driver and passenger blades are frequently different lengths on the same vehicle.
