can you put windshield wipers on backwards

The second is the optional wiper which is on the higher levels of trim (Lemans, GTO) and optional on the lower trim levels. (Tempest) This has the square wiper motor and single arm wiper blades. The first is the standard system which is primarily on the lower trim levels. Two different wiper systems for the GM A body cars from 68-72 Could you check you switch to see if they match? Thanks much If as you said that the switch grounds the wiper to work, why would the switch be grounding one spade in the off position? (I think I'm out of my league here). I checked your pic of the switch plugged in and the wires are in the right positions. Did all the continuity tests again and they're the SAME. The silver spade that operates the push button washer rivet was loose so I fixed that, cleaned her up and put her back together. I don't understand how it works, but I took the switch apart and found nothing broken inside. On the second copper spade that's next to the washer spade that is silver in color, in the CC position I DO get continuity, and the second position I DO, and the full CW position I get NO continuity. The first click CW AND the second click I DO get continuity to the case. Other photos are from my 68 GTO's harness (to be installed)Ĭlick to expand.I opened up the wiper switch today but checked it before with an ohm meter from one copper spade that's by itself to switch case I DON'T get continuity in the full counterclockwise position (OFF position if it was working right). Photo of the wiper motor is from my El Camino and the wire colors are slightly different. The two wire plug Black/Yellow wire (12 volts from the washer pump) should be to the right and the Black/White is to the left. The single wire plug (Black/Blue) should go to the right. Hard to see but they are to the lower right of the washer pump plug. If the wiper switch is grounded properly check the plugs (2) on the motor. The Black/White wire goes to the switch and is the pump ground whenever the switch is pushed in. The Black/Yellow wire is the 12 volt source and jumpers to the #2 terminal of the motor. Unless its defective, the wiper switch is hard to miss-wire but check the wiring (photo) anyway. Use an ohm-meter from the switch housing to a good carbody ground to verify. Make sure the ground strap behind the switch is grounded properly.

The wipers operate by grounding the Black and Black/Blue wires from the motor through the wiper switch which should be grounded. I'm assuming you have the optional (hidden) wipers and you have little experience as an electrician.
