Ok I just put my flasher in and a new directional signal 20A fuse as the metal end was loose from the glass but still OK.

After doing the above I went from> having no turn signals and pressing on the brake showing turn signals on like brake lights


to: > now having hazards on all the time regardless of the hazard setting (in & out).




Bad ground or did i muck up something in the turn signal re-assembly?

The hazard connection inside the column is not clear to me.

 

It has nothing to do with a ground if your hazards are on all the time...regardless if the switch is in or pulled out.

Do you have a wiring diagram????

DUB

 

Hey DUB, Thanks for replying, been waiting anxiously

Yes, I have schematics. Its just strange that the symptoms changes after just pulling the flasher & fuse and testing it on the bench.

What I don't understand is how the hazard switch works mechanically. Electrically it must be a make or break, and must be internally damaged or not connected well inside the column. All, I saw (and is pictured) was the metal part coming out towards the driver from deep inside the column.

 

Humm after locating the circuit on the schematic it clearly indicates that there are two separate "flashers" one for the hazards and one for the turn signals. I only found one in my fuse compartment. I will have to look at this again....

 

Unless the hazard flasher is located somewhere else there is no hazard flasher and must be shared with the turn signal. My schematic (from Haynes manual) for the 1971 must therefore be wrong.

Confirmed my ASM for the 1971 shows only one flasher unit for both hazard and turn signals

 

71 schematic shows separate flashers for signals and hazzards. The one in the fuse box is for hazzards, the signal flasher is behind the passenger side lower dash and can be accessed by reaching under and pulling it out of its clip. If you will remove the signal switch and correctly attach the hazzard switch to it and replace the hazzard flasher, you will probably have all of it working correctly.

 

Ok while I was out in the garage I found that your right '75! There are two different flasher units. One just like you said under the passenger dash (turn signal) and one in the fuse box (hazard). How nice of GM to be distributing all this stuff all over for me.

Now trying to understand what you mean '75

" If you will remove the signal switch and correctly attach the hazzard switch to it and replace the hazzard flasher, you will probably have all of it working correctly."

Do you mean tear apart the steering column and remove the turn signal switch assembly and connect the hazard? Or do you mean something less invasive>?

 

In one of your pictures it shows the metal actuator connected to your hazzard button. Than metal piece is supposed to connect to the lower part of the turn signal switch inside the column. What I believe has happened is that metal part is not connected and the hazzard part of the signal switch is switched on causing the wierd problem with the signals.

 

'75 thanks for the fast reply. That must be it because when I reinstalled the turn signal assembly I did not do anything with the hazard actuator and thought about it but just continued on with getting the column together.

Any pictures or drawings on how this actuator "fits" into the switch assembly? I have no clue since its all buttoned up.

 

If you google search Jim Shea, you will find a complete breakdown of the steering column and step by step instructions, he is/was one of the engineers for saginawwhen this was built and is active here for assistance.

 

Ok, wow I did not know that about Jim! how cool is that and how lucky we are to have him here! I will re-look at what he sent me and will update everyone so I can get this thread closed!

'75 thanks for your help! I owe you on brother

 

Calling ............. Jim Shea

Hey Jim was wondering if you had any more info on the hazard assembly as it mates up to the switch assembly in the steering column? All I have is my picture from post#38 and this blow up of what you sent me a link to. Neither of which explains or indicates how this hazard/switch assembly comes together.

 

I'm working off memory, it's been a few years since I had one of those apart. I think you will need to remove the signal switch, then remove the **** from the metal actuator piece. The metal piece slips up into a groove in the bottom of the signal switch, then when the signal switch is screwed into place in the column, the **** can be reattached to the metal actuator piece.

 

The HAZARD SWITCH is made into the turn signal switch.

IN post #38...the lower arrow that points to that piece of steel....fits into the turn signal switch in a SPECIFIC SPOT that is made into the underside of the turn signal switch....so when you are lowering the turn signal switch into the column...the bottom of the steel bracket that you just put into the underside of your turn signal switch fits into a small pocket in the casting of the column housing....so when you connect the HAZARD **** to this steel plate...and push and pull it in...it works your hazards.

IF you can work the hazard **** in and out and the hazards stay flashing. I think you have a defective area of the turn signal switch BECAUSE...if you do this and are looking at the turn signal switch when you get it bolted in place...you will actually SEE the section of the turn signal switch that is your hazards moving to the right (pushing in)and then back to the left when you pull the hazard ****.....and the 12 volts that is in the turn signal switch....that when you PUSH IN on the hazard ****...pushes a circuit assembly over and THUS...causes all four turn signal wires (one for each light) to NOW become 'powered up' and light up. BECAUSE the SAME WIRES that make your turn signals light up and the SAME WIRES for your hazards.

DUB

 

I should have just agreed with what you wrote.

DUB

 

I think your answer was more clear and detailed.

 

Sorry, I have not followed this thread the last several days. I was out of communication with the Forum over that time.

First of all, the Hazard Switch Lever is only used on the 1969 through 1976 Corvette T&T steering columns.
Here is a drawing of the Hazard Switch Lever.


The narrow end (on the left) presses into a receptical on the underside of the turn signal switch. The wider end sits on a shelf inside the turn signal switch housing. You will note a #6-32 UNC tapped hole in the lever. When assembled correctly, that threaded hole will align with a hole in the side of the turn signal switch housing. The hazard **** and screw will reach through the housing and screw right into the lever.

That lever is very easy to forget and sometimes will disengage from the turn signal switch and drop down into the guts of your T&T column. Or you might just forget to engage it to the turn signal switch.

Jim

 

Thanks '75, DUB & Jim for the reply very helpful.

What happened with me was during reassembly I did not attempt to fit the hazard lever into the switch. I merely left it where it laid as seen on page #38. I did not know it needed engagement. BTW the hazards never worked previously so I was not thinking I was going to try and fix it.

So if I understand this correctly one end of the lever needs to go into the switch (I suppose I can figure out where exactly after I remove the turn signal switch when I pull it again). How ever the other end fits on the column "shelf" making this lever essentially float? Is this correct?

I must have pinched the lever causing funky contact issues.......

 

This part does not 'float'....but it obviously pivots. The small end of this lever that fits to the underside of the turn signal switch (which you will EASILY FIND) fits snugly. AND the other wide end of the lever...when you look with a good flashlight fits into a special area.....and it secures the bottom of the lever so you can push in and pull out on the hazard bottom and make ti work your hazards.

When you find that small square section on the underside of the turn signal switch....pull it outwards away from the center of the turn signal switch.....which would be like you pulling the hazard **** and I bet that your hazards STOP flashing.

LOOK at post # 7. It shows what you are looking for.

Thanks again guys! Dub #7 was exactly what I was referring to! thank you for the link!

you guys rock!
