Re: 68 dash switches grounding
Sean is right; the wiper switch needs a ground. The other switches do not. The instrument cluster ground is a very common problem on 67 and 68 models. An alligator lead is a good troubleshooting tool. Hold the wiper switch in your hand and use the alligator lead to ground the switch body to the under-dash. Flip the switch and the wipers should wipe.
