New "Mad Max" subscriber, bought a 72 240z about a month ago. Last night at midnight, leaving a bar in the rain, turned on the wipers. The arms moved about 30 degrees and stopped. The wipers have been working at both low & high speeds until now, but now nothing happens. No fuses are blown. I'm mechanically & electrically competent. Please tell me how to troubleshoot this problem like is it the motor, the linkage, the switch, electrical, etc. It's been raining a lot here in San Jose, CA. Thanks for reading!
