Troubleshooting the Combination Switch Wiper Side and Harness Plug
The Datsun 240z had a different combination switch for each year. The switch changes the continuity to ground for the circuit. Troubleshoot the wire harness plug first, then the combination switch. The blue/red wire is power from the fuse box. The contacts in the switch may be have carbon build up and need a good cleaning.
