i cant find out why my head lights wont go up or down. i replaced the switch and the fuse and nothing. when i roll them down manualy and put the fuse in they automatically go up and stay that way. if i try to roll them down with the fuse in they go down and back up. i tried the connector (white) to the motor and put 12v to it it clicks and thats it. and i testing the wrong wires is there a bad relay?? and helped thanked

Turn the switch just above the headlight switch. See manual.

There is a small **** above the larger headlight **** which is used to flip the headlights up but not on. Check the functionality of this ****.

i replaced it with another switch and i still had the same problem im convinced that it is not the switch but something else.. . . . if i roll them all the way down and put 30amp fuse in they go up and stay that way... if i try to roll one of them down while the fuse in it will go down and pop back up.

You did turn the switch above the headlight switch and still have the same problem.........but never made a reply that you turned that switch? We don't know if you did.......or not.

Has anyone had this Problem before?

Retract fuse any good in the engine bay?

What year RX?

HAILERS2

IF I had a series five car with the retractors not working and the HEADLIGHT and RETRACT fuses were good.............and the connections just below the RETRACT fuse is on good at the bottom of the engine bay fuse box (WG or white/green wire) and I"d already checked and made sure with a meter that the WG is hot at the retract motors plug...........I'd do the following.

I'd pull the elect plug off the headlight switch. Then with a jumper wire I'd jumper b/t the RED wire and the RED/YELLOW wire and after I did that I'd jumper b/t the RED wire and the R/L or red/blue wire.

Red/yellow would make the headlights retract and the red/blue would make 'em come up when jumpered one at a time to the RED wire. See the attached diagram.

IF they do work like that..........could be a bad relay in the headlight switch or I have been given to understand the series five CPU is tied into this circuit in someway or manner.

I assume the headlight fuse is good in the engine bay since the lights come on. RETRACT RELAY or its path to the retract motors is suspect and if it's good then the path of the red wires power in the switch to the Red/Yellow and Red/ Blue is suspect and maybe, just maybe the CPU on a series five could cause this problem somehow someway. It's the last thing I'd suspect.

I vaguely remeber some series five cars having this problem on this forum and the CPU was the problem. I don't have a series five and have not much interest in how series five work. Series four is similar but there's no CPU involved as shown in the attached jpg above.

Makes me wonder that if you reached over there and pulled the plugs off the CPU whether or not the headlights would retract. If they do..........CPU related.

Read post #12 of this thread: https://www.rx7club.com/showthread.p...headlights+CPU

Basically he disconnected the CPU on his series five and the headlights worked meaning the CPU is/was kaput. See if that's the case for you.

If I disconnect it will I have turn signals? And I did put my battery in wrong when I first got the car and I recall taking the CPU out to look for damage but I think it has been bad even before I got the car I will check it asap

HAILERS2

There are three plugs on the CPU. Pull off only the one with 8 pins in it as is shown in RED in the attached jpg. The Turn signals are in the plug I colored Blue ...so if you don't disconnect that one then you''ll keep the turn signals.

Electrical boards inside the CPU can be bought from Mazdatrix as replacement parts. Cheaper than a new CPU.

EDIT: Looks like you'll lose your horn function if the 8 pin plug is removed.

I'm not sure right now which board you'd buy to fix the headlight problem.

HAILERS2

IF pulling off the 8 pin connector fixes the headlight problem............then replace the board shown in the picture outlined in RED.
