These @#$!^ blinkers!

Ok, THis is the second time I have posted about these blinker issues and still can't figure it out.

Here's the deal :

I have a new wiring AAW wiring harness installed as well as new turn signal switch. Parking lights work fine, Drivers side blinkers work fine, BUT, when I try passenger side blinkers , both sides blink as if hazards are on. I don't know if it is a ground issue or what. Any help would be more than appreciated. Any ideas?

It's a 67. Yes it has a new AAW dash harness. It was a full front to rear wiring harness.

Re: These @#$!^ blinkers!

Remove one drvr side bulb and view the results, then chose the other drvr side bulb and view.
The bulb affecting the blinkers will have a probem with the t/sig switch.
I suspect the t/sig switch is miswired. The switch has one power wire from the flasher and four separate circuits out.

Re: These @#$!^ blinkers!

I'm wondering if the dash harness' steering column-turn signal connector has a couple of wires out of order..
I'm not familiar wit 67 wiring, but it's quite possible on a 69.

Re: These @#$!^ blinkers!

Ok, I forgot to mention that I had this problem with the old turn signal switch so I figured it was something in it. So , I replaced it, and still having same trouble. All the wires are matched up as far as color and how the schematic indicates at least where the turn switch plugs in to connector. Is there somewhere else I should look for miswiring?

Re: These @#$!^ blinkers!

Each end of the harness has its own ground; rear lights ground through the light bezels, so make sure the pass side has good conductivity, front lights have their own ground wire. And I'm sure you've been here before.

Here's what you can do to assist in troubleshooting, remove the flasher and replace with a jumper. Drvr side should still light when selected. Pass side should come on as well, and maybe even the drvr side.

Unplug one pass side light and view results. Drvr light still on?
Unplug both lights, drvr light still on? Bad harness.

I would imagine the original harness and t/sig switch, eveything worked good?

Re: These @#$!^ blinkers!

You ever feel stupid?

I finally figured out what it was. After checking and rechecking every wiring connection I could find, I started messing around with bulb connections and discovered that the rear passenger taillight had an 1156 bulb in it rather than 1157. Not sure if I put it in there or if it was one that was already in there, but, it fixed it.
Just goes to show that you should do what everyone saysand check the simplest stuff first. Thanks to all for input. One more think off the checklist!

Re: These @#$!^ blinkers!

Don't feel bad.. That's a great lesson learned. I never knew the wrong bulb would do that.

Re: These @#$!^ blinkers!

My brother couldn't believe it either , Steve. But, when I put in the 1157 bulb it worked like a champ. Not sure what the difference is in the 2 bulbs, and I'm not questioning it. It works now, so, I'm lettin it be. Just wish I would have started there before I bought new switch and tore thru column several times and looked all through dash, but like you said, a good lesson learned.

Re: These @#$!^ blinkers!

An 1157 is a double filament bulb and has two contact buttons on the bottom with different position keys on the base.
An 1156 is a single filament bulb having one contact on the bottom and symetrical keys on the base.

The 1156 contact bridges the gap between the two socket contacts of an 1157 socket.

Re: These @#$!^ blinkers!

The 1157 are a single power lead with one element and the 1156's are a dual power lead with 2 elements. It is impossible to place a 1156 bulb into a 1157 socket and vise-versa as one retainer tang is higher then the other. Also the 1156 has a 2 contact base where as the 1157 only has one in the center. Make sure the contacts are clean and spray with Rust Check ;o)
