OK guys- it has been a long time,,,, since my turn signal flashers stopped working. All four lights are working, but not flashing.. How do I determine which flasher is out? Can't find the answer in any of my manuals or books. Thanks!

 

"which flasher" - if you mean flasher relay, there is only one. It is up under the dash on the driver-side, near the side. There are a collection of electronics there. I think on the 79 (which is unique to that yr I believe) is a silver cylinder with a 3 -prong harness connection at one end....start there.

Stu, where can I go on-line that will give me an accurate part number for the 1979 Flasher relay? My problem is that if I get it out or hire someone to get it out, I need the part or I will be down while everyone searches for the part.

 

Mazda factory number will not help you much as these are NLA from them. There may be component-maker numbers on the housing that would help in locating a replacement.

Black plastic rectangular relay with a 3-wire connector on the bottom, attached by a screw through a tab at the top. right near the ECU, above the driver-side kick panel.

Bit of a challenge to reach the screw if I recall.

NOS One on ebay right now if you can stomach the $$ burn...

Yes he is keeping my part hostage on eBay!

 

 

If you haven't gotten your flasher working yet, I bought one of these a couple months ago and it worked. I'm using it as a spare as I was able to disassemble my old one and clean up the contact and it is working again. Double check the connection style as I noticed when looking on RockAuto they had a couple different arrangements for the 3 prongs, and according to Amazon, the part "This does not fit your 1979 Mazda RX-7" so I dunno? Maybe they had different styles?

 

So SunRed, Let me understand this right---this Amazon part worked in your 79?

 

You can get a digital unit and its easy to make a 2 wire jumper from the stock connection to it and it will work fine. You will lose the clickety-click when it blinks though.

 

Yep, that part worked in my RX-7. Check your connectors on your stock unit to make sure they look the same. I've seen different looking connectors on different sites for the same year RX-7.

The flashers they show on RockAuto for a 79 RX-7 looked nothing like the ones in my car

The flasher they showed for the 79 Mazda 626 was a dead ringer which is what the one on Amazon(I bought it on amazon for free 2-day amazon prime shipping and returns if necessary)

So does this Tridon flasher still do the clickity-click when flashing?

Great find by the way. I should have searched harder on Rockauto. Looks like standard and airtex have the part specs goofed up for RX7. If you look at the GLC it shows both the 3 prong and 2 prong flashers as being the correct part. One has to be wrong. That Tridon part says its good for GLC, 626, RX3 & 4 and bunch more.

 

Just wanted to report back to you guys and say that the Tridon part from Amazon worked fine. I took it in to my mechanic, and 30 minutes later and $40, it was installed! He had to make some modifications to make it work. Yes the mount will not fit. But he stuck it up there and we are a flashing!! Thanks again!

 

Glad to hear it worked gosman!
t_g, the only difference from the stock one is the lack of the tab for hanging it under the dash, same ole click click sound.

 

Excellent, I miss t he clicking since I went LED.

 

Here you go, my new favorite video:


I'm sure you could wire in your own click sound, maybe just a relay would be enough of a sound?

 

Ha Ha! I keep my new/old clicking sound!

 

Here's a clip of my 79 blinker opened up, showing why you get that clicky sound.
