I have a1980 el camino with standard non delay wipers. And the switch is mounted on the dashboard. I have already a assessed that the motor is fine. And found out that the switch isn't getting supplied power unless in acessory to the ignition switch on top of steering column. I just replaced the ignition switch a week ago. But havmt used the wipers in a long time so idk if it could be that. Could it be the lock cylinder? Is there another switch or relay or something on the steering colum between the key and ignition switch? Someone please help me cuz I'm losing my mind.
