Yes I know that the S4 and S5 turn signal switches are different and cannot be interchanged. My searches kept comming up with people talking about the actual turn signals, outside of the car...sooooo here is a back story

I bought the car and the turn signals didn't work...checked the fuse, that was fine. The bulbs were fine because the hazards light up. When flipping to my brights, the switch works fine. When engaging the turn signal (left or right) there is no clicking, the cluster arrows don't show up...it seems dead...(as I read more I'm thinking it doesn't have to do with the switch, but rather the CPU...I don't know though, I'm a noob )

I assumed the switch was the culprit and had an extra one laying around so I thought I'd swap them out. In doing so, the relay up by the radiator would buzz and tick and the headlights would light up as soon as the battery was reconnected. So I now know that the switch isn't the correct series. So my questions are:

When you have the turn signal switches out of the car and in front of you, how can you tell the difference between S4 and S5? Is there some sort of visual difference? How can you tell what series harness (the one with a blue plug on one end and it branches into two plugs, one for the elongated headlight switch and one for the turn signal switch) you have?



I'm having lots of issues with that side of the cluster surround, so I'm trying to gain some knowledge before I start troubleshooting

Thanks in advance for any insight,
Geoff

Bad CPU

and the difference between the switches is that the S5 one will be more angled on the mount, while the S4 one will be slightly shorter and the curve of the dash bezel will align up to the switch almost in the middle.

GeeHawf

so how do I go about resolving the problem...

cuz i think i fried my headlight switch as well, because now I can't use the biggest **** to flip the headlights up or turn them on...I took the switch out of the bezel and there is something rattling on the inside...

Should I follow the tutorial in the archive on rebuilding it? Or would that not fix the problem...

Icemark

The wrong turn signal switch should only effect the High/Low beam, and not the headlight switch itself.

GeeHawf

ok so I have the correct turn signal switch (in good functioning order) because it works the high beam and low beam...

I have a bad CPU (and don't know what to do....but I can search about that later)

My headlights don't work though...I had an issue with the harness wiring and I tried to fix it and something ended up smoking and blah blah...I took the switch out and something is rattling on the inside of it...the headlights wont go up with the big ****, but go up with the servicing ****. I can't turn the headlights on, but when if I hold the lever open(for the high beams) they will light up, they just don't stay on by themselves....

So should I follow the rebuilding my headlight switch tutorial in the archive? Since something is rattling and its just acting up...


Thanks for all the help Icemark,
Geoff

as far as turn signals, order up a new flasher board from Mazdatrix. The 86-95 all use the same flasher board in the CPU.

From your description you burnt up the headlight switch. You will need to replace it. I no longer stock the headlight switches and your will not be able to rebuild one that has burnt parts up internally. Probably ebay or the for sale/ wanted section here is your best bet for finding another switch.

GeeHawf

I wanted to move this up because another question arose after more searching...

My new question is regarding the turn signals again...
I saw on other posts that you (Icemark) were telling people to get the new flasher CPU when both their turn signals didn't work along with the hazards not working...Also most people were hearing a click when they flipped the lever...


So I guess I'll restate the problem and hope that you can point me in the right direction since I am really new to all of this...

Problem: When engaging the turn signal lever, nothing happens. The arrows in the cluster do not light up, the bulbs do not flash and the relay does not tick. When engaging the hazard button, the arrows in the cluster DO light up, the bulbs DO flash and the relay CAN be heard

I hope that doesn't make me sound like an asshat because I really am just looking for help

Thanks in advance,
Geoff

Are you sure the harness for the turn signal switch is plugged in and the correct harness for the series?

If the hazards work fine, it pretty much rules out the CPU except for two connections, and the odds of it being both that have failed at the same time is pretty minimal.

GeeHawf

I assume that the harness is plugged in correctly since I can successfully turn the high beams on, and reconnect the battery to the terminal without any relays going crazy...

I wish I knew more about electronics so I could help out more

GeeHawf

any ideas?

Not the cpu flasher board since the hazards work...not the bulbs or the fuse

When i flip the lever, I don't hear the relay, literally nothing happens

Icemark

You'll need to check the output from the switch at the CPU with a multi-meter

GeeHawf

is it too much to ask you to help walk me through this...cuz i've never worked with electronics on my own...

I went out and bought a digital multimeter (attatched picture) and i know how to hook the probes up but I don't know which slots to put them in and what setting to use and its quite overwhelming

So if you could be as lamen as possible and tell me how to set up the multimeter and where to put the probes to give you the reading you were looking for, i'd be quite greatful

Looking to the left of the clutch pedal (attatched picture) I know that the blue plug is the one end of the harness that goes to the headlight switch and the turn signal/high beam switch, otherwise its a jungle down there


If I can take more pictures or be of more help, please don't hesitate to tell me what to do
