Electrical Problems (signals and wiper systems)

[DJ_SLapo]

First problem:Turn signal system is not working like it should. Blubs and fuses are good. The issue is the hazard switch doesn’t blink the lights when the switch is pushed in. When the switch is pushed in (on) I can’t use the turn signals. Other than that my signals work fine.

Second problem:The Wiper system is not working at all. I tested the switch and the motor. The fuses are good. I did a conductivity test on the switch and it passed. Also, I tested the connector between the motor and the switch for voltage. I tested the leads for high speed. The connector on the body side is getting 12 volts when the switch is all the way down on high speed. When the switch is up in off position it is really off. So, I was thinking that the motor is died. So I tested the motor by cutting wires and using them to hard wire them from the battery. The motor works and moves when is hard wired. So my next step was that the amp (the green box on the driver side) went bad. So I went to the salvage yard and got two of them. I tried all two green boxes and still no luck.

Thank in advance, Steven.

The hazards get their power from the signal power at the turn signal switch. You can check the hazard switch (page 35 in the EL FSM). And you have power to the motor, and you tested the motor out of circuit.

I'm thinking its a chassis ground issue. Check for corrosion, rust, etc. Also check connections (CRC QD contact cleaner works great)

tested the motor out of circuit.

Yes I have. I even taken it out and put in a friends 240sx and it ran. I'm just running out of ideas. I have also ordered a new. But, I'm going to check the grounds. If I can find any. A little lost in where to find where they are grounded at.

could be that fat wiring harness on the driver side fender. if you are super slammed, maybe you've rubbed on them.

[breadbox]

he just has like an inch or 1.5" drop, so I am not thinking its that but we can look.

I have a similar problem with the wipers first thught it was the motor test it out side and works then i said it has to be the switch bought one new and nothing water does come out so I don't know what could be if any ones know help us both.

In my case I washer mode doesn't work also. You maybe fixed than me. I have two more months till my next safty inspection.

if the black wires are measuring 12v at the unit your ground is fine. tcu seems to be a critical component

Would that be the black or white box on the driverside?

I have changed the white box with a spare one. And nothing still works right. I'll post pictures of the car in a few days.

What black or white box are you guys refering to? Well my problem still there don't know if my green box is out. The car is been at the garage for 3 years and at that moment they worked fine.

green box in the engine bay close to your master brake cyln in the wiper relay. Or, I think that is. As for the black or white box. They are near fuse box on the drivers side. You would have to remove the kick panel cover to get to them. They are both held on with screws.

[sr_240sx]

Yeap the relay box I checked them the only thing missing is the green box but I don't have another to try my rear wiper works so I don't know. In your case it has to be electricity.

rear wipers have their own amp

[sr_240sx]

that's good to know!!! Now I will try to find a green box a test it.

[sr_240sx]

I changed the green box and now there is a clicking noise coming from the green box that before was not doing but no wiper movement yet. Any ideas? Did you solve your problem?

[sr_240sx]

The wiper amp is a green box next to the brake master cylinder. The TCU is near the underdash fusebox area. The wiper amp controls the autoreturn function. The TCU controls the time delay of the intermittent wipers.I found this info. maybe this is or problem!!!!!! the Timing Control Unit= TCM

Yes this all right. I have swapped all these parts and a rebuilt wipper motor and still no good. The amp is at location E50.

I found the problem the harness was broken on the baterry area I had a electromecanic coming home and fix it now I had to orther the right pivot and both rods from the wiper system. Did you check the switch?? the the level on the sterring wheel? that could be!!!

I swap out with another one from the junk yard and still it didn't work. But then again the both switches could be still bad. Is there anyway I can't test them? I have the FSM but when you zoom on the harness you can't read the pin out. Where near the battery was it broken at? It could be a common problem for me to trouble shoot at.

Do you have a front mount intercooler??? when I made the hole for the cold pipe some how I don't know how I cut a piece of the harness on the baterry tray the harness is atach to the radiator support (wall) it goes on the fender under out side also a frind of mine told me that it happened to him that the tire hits the harness on the fender and brake it. I have a switch that is in good condition I can send it to you. that way you would know that one is good. If you check the motor out side and works is 1. the switch 2. the amp (green box) or the 2 boxes inside or 3. a broken wire need to check if there is visible wire damage check the harness. [email protected] this is my email just in case I also have the 2 boxes that goes inside wich I text.

The wiper problem solved. The fuse link was loose making the motor not work. I paid 57 and some cents to get it looked at. Good deal?

For the next problem is installing the wiper motor. I go the motor back in but for some odd reason the motor stops the wipers where ever. And sometimes gets the blades stuck on the bottom of the windscreen.

[breadbox]

LMK if you have time to come over and mess with it. Atleast you can pass inspection soon. Now that the wipers work.

Wonder if -RJ- got inspection yet?

[Didderson]

Hey vancouverbc thanks a ton for that info on the tcu!

Why didnt anyone tell me that when I asked about my wiper timing not working lol... its only the timed switch. fast and superfast still wipe so it's workable but very gay to drive like that atm.

I need to fix my dome light over spring break too. yeah this car had a jackass 'install' a radio before. fail

[DJ_SLapo]

Would the TCU control where the wipers stop?My wipers stop where ever they want. Also the Green box in the engine bay makes a clicking noise now. I'm going to try to replace it with a junk yard one and see were that takes me.

[DJ_SLapo]

flasher problem solution:Same as the wipers. The fuse link was broken.

Still working one how to make the wipers stop at the bottom of the windsheld and not the top

[s13k1d]

i dont have a diagram in front of me. but i believe there should be a park circuit in the wiper motor assembly. its purpose is to return the wipers to the bottom of the windshield. have you put another wiper motor in to see if it fixes it?

[DJ_SLapo]

Wiper problem solution:

When I got a new the wiper motor it didn't come with the arm. I transfered the old arm to the new motor. Then I did the install like in the factory service manual. But what I didn't know is how the arm goes. The arm has a key lock so you can't install the arm wrong. You can just everything is will be backwards like I did. So I took the arm off and installed in 180 degrees the other way. I hook everything back up. Now, the arms return back down.

I was looking at this linkhttp://auto.howstuffworks.com/wiper1.htmAnd it gave me the idea that the arm link was on backwards

[breadbox]

So the hatch is all happpy now? or there are still some demons somewhere?
