Headlights won't pop up

1984 RX7 FB

Front headlights stopped popping up, however I tested the connection for resistance and it was getting connection.
This only recently happened, before it was working fine.
The actual light turns on, dashboard light also comes on.

Also my hazard switch doesn't work, but fuse for it is brand new and there is resistance from the connection there.

Is it possible that both motors busted, or is there a relay seperate from the motor than from the lightsource?

P.S. I'm not sure how to read the wiring diagram.

edit: not sure if the Wiring Diagram is explaining this but, for headlight retractable the cord will be red/yellow so I should cut it open and check it for connectivity? Anyone know what setting on the multimeter I should use, and what would mean good and what would mean bad? (and general explanation if you will!)

Thanks for reading into ths.

Check the fusible links over near the battery. These regularly give troubles in gen 1s. There's a mod to use the later model plug-in fuses on Aus-rotary and probably on here too. The hazard light problem is most likely in the switch.

The popup headlights are most likely the fusible link or other wiring. It is unlikely that both motors would go out at the same time.

The hazards could be several things. In both of my cars I I get a buzzing sound when I turn them on. The flasher electronics is in the computer module under the dash (behind the fuse box) and is not a separate device that can be replaced. In the car I converted to an EV the flashers have started to work again. I don't know if this is because I have bumped the car voltage to 13.6 all the time or something else. It has never gotten to the top of my list of stuff that needs fixing. Check the switch but if you hear a buzz from under the dash when you try to turn them on it is probably in that module.

Go to Advance Auto on Alton RD, and pick up the fusible links from the 2nd gen.

annnd fixed, bought those bussman fuses and it worked.

Now to just figure out my hazards!



before switching to bussman fuses, does the back look alright? the top Blue / Red stripe wire is very loose and not actually connected.

So it was just a bad fusible link?

My headlights are not popping up, but are turning on. My fusible links are fine. What could be the issue?

It can be a bad/dirty light switch on the stalk, bad ground, broken power wire, bad fuse. What happens when you remove the cover from the top of the light motor and turn the little ****? It takes a few turns to get it to move.

That is a lot to check out and I will get on it for sure! I read up on using cleaner before taking it fully apart and I plan on doing that later this afternoon. I also think I need to look at my grounds, however the fuses are all good and I checked the motors ability to move by raising them manually. The lights went up fine, but do not respond to the switch to put them down just as it does not raise them up with power. Worst case situation I can open them manually when I want to drive it, but I would really like to find why the switch on the steering column does not work as well as the switch specifically for raising the motor up. That is what has be really confused. Neither of the switches seem to send power to the motors. So I assume the power in to them is the problem. But they still turn on all the lights, just not raise the motors. So its confusing.

Does the lights up switch by the hazard switch put them up?

I cannot get either of the switches to respond and raise or lower the lights. The switch on the steering column or the switch on the console. The switch on the steering column does turn on the headlights and the high beams as well, but it does not raise them.




I just need to know what the color and gauge the wire that feeds these switches so I can assure they are getting power, then figure out if the power is leaving the switch and then see if the power is getting to the motors from them. I can look at them but I do not know which is what and if neither are getting power or if both are I could end up doing something wrong.

Looks like the wire color is red (R) and whire/red (WR). You're going to have to start taking voltage readings are this point. Measure the voltage at E-03 and E-04

You sir a gentlemen and a scholar and I thank you! I will get on testing wires! Thank you!

I'd be surprised if your problem was due to suddenly losing power through a wire. Not sure how you checked the fusible links, they can look good but be corroded inside. Sometimes if you wiggle them a little they will make contact again and the lights will pop up. Another thing to check are the relays attached to the side of the headlight motors. Small rectangular boxes under rubber covers. Sometimes, tapping on them brings them back, or open them up. There are a set of contacts inside you can lightly sand and clean. Every single time I've had head light problems, its been either the fusible links or those relays.

If you don't have a meter handy here is one way to narrow it down.
  • Since the headlights work then the top fusible link is good and the UP circuit is powered from there.
  • Since the headlights will not move either direction when manually positioned it has to be something common - retractable headlight switch (RHS) , Bottom fusible link, wiring or both headlight retractors
  • Switch the retractable headlight switch (RHS) to UP - the headlight cleaner motor should run when you actuate it since it gets it's power from the UP side of the switch. If that is the case then you may also be able to hear the relays on each retractor clicking. If not it's the RHS or the wiring from it to everything downstream.
  • If the headlight cleaner motor runs then it's got to be the bottom fusible link or wiring at the headlight retractors or both headlight retractors.
My bet is on the lower fusible link or it's wiring since you cannot get them to go either direction after manually closing and opening them or the HRS.
