Wipers, Hazards, Turn Signals.. oh my!

Winter is upon us in California, or as I like to say, ‘spring time’. Only because it’s just a few rainy months till the only other season: summer. There’s been a long intermittent problem that wipers haven’t worked, and with the coming rain, I thought it would be a good idea to get that fixed. Along with the trusty 280z manual and a little luck, all three systems worked brilliantly.

Previously, the wipers weren’t working because of a corroded contact in the steering column switch, in which a few on/off turns cleared it up. This time it wasn’t the case. Not only were the wipers not responding, but also the blinkers and turn signals had also failed! My hunch was that since the same lights used for the hazards / turn signals were still turning on, it was perhaps a relay or fuse. Fuses looked okay, so on to the relay.

Both the hazard and the turn signal relays are located under the steering column area in the cabin. Yanked both of them, headed straight to the auto parts store, and was greeted with a, ‘whoa, those are hecka old’. Unfortunately, O’Reilly’s only had the hazard relay but luckily: it was the only one I needed.

The original hazard relay for a 1977 Datsun 280z is a Niles HF566-12V, 32CP Max 6, 80C/M relay.
The replacement hazard relay is a Littlefuse FLR577BP 12V relay with the same markings.

I reconnected everything…low and behold, the hazards flash. Doesn’t hurt to try the others, right? The turn signals started blinking, and the wipers precariously make their way across the windshield. Nice – ready for the rainy season.

Old relay – found just hangin’ out…

Hazard relay - Littlefuse FLR577BP - Daily Datsun

New relay – still hangin out.

  1. If you want to improve the performance of your wipers/hazards/turn signals even more, I suggest you do the following:
    1. Remove the wiper linkage, blast out all of the 30+ years of crud, and rebuild them as described in this thread at Classic Z Cars – http://www.classiczcars.com/forums/thread47611.html
    2. Replace the bulbs in your parking lights and turn signals with LEDs. This thread describes what some of us have done, including using updated electronic flashers – http://www.classiczcars.com/forums/thread40600.html
    3. Clean up your turn signal switch as I described here on my blog – http://fiddlingwithzcars.wordpress.com/2012/12/04/turn-signal-repair/
