I determined the reason my passenger headlight won't pop us is because of a bad relay. I swapped the LH relay with the RH relay, and the problem followed the relay. These are the ones out under the hood bolted to the fender just to the rear of the headlight.

Is there anything special about these relays? Does it have a unique plug? NA or NC? Do I need a Mazda oem part or what's a good source?

This is for an 87 TII if it matters.

 

When you unplugged the relay how many wires were in the plug and could you discern how many of those wires in the plug went to the retractor motor itself? You'll have to wait for HAILERS to chime in with the possibility of being able to use an aftermarket automotive relay or relying on having to find a stock replacement to fix the problem. Also, not sure what would happen if you wired the wires from the bad side to the working side so one working relay could do the role of two or not.

 

I think there were 5. I'll have to look at it tonight and confirm.

 

I got a passenger motor with relay if you need to get one.

 

Did you resolve this already?

I find no wiring diagram for this early model retract relay located out of the retract motor.

But. You have three wires on the top row and one on the bottom.

The coil is powered by the green wires in the middle of the top row and the black wires on one end of that row.

So now all you have left is the bottom rows one wire and the last wire on the top row.

Sooooooooooooooo I'd buy a common auto relay and have that relays coil powered by the green wire on one side of the new relays coil and the black on the other end of that relays coil.

Then the new relay will have two contacts that are normally open and I'd put the leftover two wires to those two contacts. Make any sense? IF I had a spare auto relay laying around I'd check that out myself. Maybe tomorrow I'll find a old radio shack relay laying about and do that by making some jumper cables/wires.

I left out that there are two green wires in the middle and two black wires in the end socket. Not a big deal. I just treated them as one green and one black above.

Or I can give you the part number on that stk relay.

I bought a used one off a guy here. Hopefully that'll take care of it for a bit.
