Click on the link. I always check voltage and ground, w/o ground also, it won't work. The top wires in diagram are voltage depending on what your trying to do? The black wire is ground. You can check ground by also using a test light. One end of test light touches battery voltage, the other end touches black wire terminal. If the lite comes on, the ground is good enough to work the test lite.

Yes this is an issue on many Chevys with no recall. MOST of the time the problem you are describing is the wiper motor "pulse board", not the motor itself. Bad solder joints in the thin board, crack, so vibration and normal driving make them worse, and no contact is being made. Good news...Advance Auto Parts carries these for approx. $30, much cheaper than motor replacement. Just like wiper motor removal but all you have to do is remove (3) screws holding pulse board on motor housing, and most IMPORTANT, always put a thin bead of silicone or quality sealer around edge before re-install, this helps with vibration as well as waterproofing. Hope this helps!

You will have to change the swich that control the wiper blades cause sometimes they go bad

Well sure enough all I had to do was replace the circuit board...wish I had done this a couple months ago...it was so easy to do and will now be much easier to drive with being able to see clearly again....
