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.

 

Good Morning…

The day started at 7:30am this morning – I was so excited about wrenching on the 280Z that I was gonna get a head start at 2am lastnight! (Side note: from now on it maybe referred to as just ‘280’, we’ll see how it goes…unless i find a name for it – yes, gender-less for now).

Squeek, Squeeeeeeek – Whenever I gave it some gas, there’s always this squeek that shrilled out from under the hood. Not good if you’re looking to turn heads in the bad way.. or trying to impress the parents that this was a good buy :] My Chilton’s Datsun manual is on it’s way, but i couldn’t wait till then. So upon checking the belts, I remembered my brother’s Datsun 510 manual said something about ‘tight..not too tight…1/2″ deflection..’ haha ok, well better than the +1″deflection this thing is giving now. One wheel had a very handy adjustment screw to lift it and give the belt the right tension. I’ll certainly revisit the belts once the manual comes in, but for now….squeek be gone!

‘Ink’ Change – Popped the 280 on ramps, popped the hood, popped off the oil pan nut off with my fingers.. wait.. with my fingers? Yep, it was literally being held tight by crusty oil around it’s edges. Same with the oil filter – only loosely screwed on! nice… Even better was the primordial blacker-than-black ooze now seeing the light of day since who knows when.. 1977? It was like ink, colored from the depths of space, kinda black. 4 quarts of 10w30 high mileage later… pprrrr.

Minor Rust Work – Picked up a can of grey primer rust inhibitor to temporarily patch up the exposed rust spots before the rainy season hits. Already there’s moisture and water beads forming in the morning, so the weather is coming. Sanded some test areas to see how this stuff works. We’ve used some in black and of another brand previously on a motorcycle, but it’s only been 2 months and garaged, so this will be some real world testing. Quick tags on the inner hood (sanded, light rust), driver-side rear quarter panel (not sanded, previously bondo work), and a heavy spot under the passenger-side deck lid (not sanded, literally like a bit from the rust monster). I testing extremes to see what I can get away with.

Tree Sap, Meet Razor Blade – According to wild Bill, the 280 was parked under a tree for 3 years; no the car isn’t a cupcake, and that’s not frosting. But nothing that a good ol’ razor blade can’t handle! Cleaning the windows as a snap, and didn’t think twice about using it on the paint – why? cause the paints eventually going to go anyways. Regardless, sap’s gone and i didn’t even leave a scratch.


Wipers – Again, rains a’comin’! So I began to outfit the new wipers on the holder when.. wait a sec.. this isn’t like modern cars. Yep, it uses a pin, which fortunately, the wiper blade manufacturers have accounted for. There’s a tab that keeps in place, used the floor to help push the pin out – viola. Reversed steps to get the new blades on, and adjusted the wiper height w/ the screw to the motor. Upon sitting in the car, it looks a touch too high, so i’ll have to re-adjust that…test…aaaand the wiper motor doesn’t work. Tracking the problem maybe tomorrow’s effort.

Upcoming – Wheels? Seals? Carpet? Paint? haha let’s spin the wheel! seriously, there maybe some panasports in your future. seriously.
