Your alternator might be going out. Take it to a parts store to have it tested for free.

Well you have to define how low the voltage is. On alot of chevys the power for everything is ran right into the fuse box & the wiring is'NT always perfict, which means there is a big load coming from the same line as the Dash & your voltage gauge. Which in turn makes the voltage read lower right at the dash then it actually is at your battery.

But never the less it does't hurt to get the alternator checked & to make sure your battery terminals are in good shape as well.

How do you turn on headlight wipers on a Saab 9-3 Convertible?

First, your headlight switch must be in the "ON" position, even if your lights stay on all the time. If your switch is "ON" you simply pull the controller to engage your windshield washers. The Headlight washers operate when the windshield washers operate. Get someone to watch them as you wash your windshield or you can shine your lights onto a wall and see the shadows as they operate.
