78 camaro turn signal help

Well my turn signals have been acting up for some time now and I need to get them working properly.

I just went and got an electronic load independent turn signal flasher. That made no help. Here is as much information as I can give and we will see what you all think might be the fix for the problem.

When the driving lights are off (driving light knob all the way in):
No signals flashing on any part of the car no matter the position of the turn signal lever. The indicator lights on the dash are not lit either. Rear signals never light.

When the driving lights are on (driving light know all the way out):
Front passenger side turn signal is lit constantly and will not change.
Front driver side turn signal will light and stay lit when the lever is in the left position.
Left turn signal indicator on that dash is constantly lit when the lever is in the neutral position and goes off when you flip the lever to make a left turn. The right inside indicator never lights in any position.
Rear signals never light.

I hope some one knows whats going on as it has me stumped.

hcker2000,

Sounds like the turn signal switch needs to be replaced. Pull the steering wheel and have at it my friend.

Doc here,

Did you , or someone Else rewire the car at some point?

Sounds like the power from the headlamp switch has been routed to the Turnsignal/brake lamp circuits..

Do the brake lamps work normally?

No one has rewired it that I know of. It used to work every once in while but has stoped working now for a while. The break lights work just fine as do the head lights.

Doc here,

Check for power at the 3 fuses for Turn/Haz and Brake lamps to the devices. Use an ohm meter to check the fuses.

Next go to the column plug at the bottom of the steering column. Unplug it. Measure the Purple and brown wire for power, meter set to DCV, Scale V X 20 or higher.

IF power is good, jump from either purple or brown to Dark blue, and light blue, one at a time. Check the left and right FRONT and dash indicator lamps, the selected side should be steady on with the jumper.

THEN, move your jumper to the Yellow and Dark Green, one at a time. The selected side should be steady on, but no indicator lamps.

If you have this, the harness , bulbs and Grounds are all good. IF not Isolate the problem (hand over hand the rear harness, check the lamp bucket grounds, be sure ALL lamps (including the side markers are the proper bulbs)a cross feed here will light the signals with park lamp/Headlamp power.

IF all this checks good, then your options are limited to the harness inside the steering column, (shorting out) OR a bad turnsignal switch..replace / repair as needed.

Thanks I will give that a try. From what it looks like in that diagram the blue wire at the rear of the car is a positive right?

Ok the turn signal fuse was blow. I replaced it and tried the turn signals and signal pot was clicking like it should but by the time I got out to check to see if the lights were going it had blown the fuse again.

I checked the purple and the brown (this was after the 2nd fuse blew) wires and brown had voltage the normal 12v going to it. The purple had nothing going to it (might be because I tested after the fuse blew?).

Ok second report. Looks like brown is the hazard flasher line. Here is the information.

Brown to dark blue = front passenger (working correctly)
Brown to light blue = front driver (working correctly)
Brown to yellow = rear driver (working correctly)
Brown to dark green = rear passenger (blew the hazard fuse after a second or so of flashing)

Very Possible, that wire should feed the flasher load (flasher) side, the other side goes to the fuse panel.

Doc here,

OK, you have a short to ground on the Right Rear Passenger line to ground.

You'll need to "Hand over Hand " the rear harness until you spot the short..IF it ever had a trailer hook up, that is a good place to start. Find that, replace the wire, replace the fuse, and it should be "All Good" .

BE ADVISED: If the rear harness inside the body is a ribbon type of wire, IT WON'T Solder or Butt Splice..it is aluminum..it won't take solder, and will just snap if you try to crimp it..run a NEW wire if this the type you have.

Ok I will start at the back and work my way forward as there is a trailer plug on it. I re-did the plug the other day and that should be correct but with the hack job they did originally putting it in there may be other issues around that area that I missed.

Arg back out in the heat I go.

Well I got it fixed quicker than I thought I would. I started where I ran the wires for the boat trailer threw the metal and sure enough thats where it was.

It must have pulled on them when I scraped a bit coming from my father in laws house (he gave me the boat).
