Turn Signals

I have a 74 vette and the turn signals have stopped working. I've checked the fuse and changed the turn signal flasher. The hazards work. What am I missing here? Is there a separate turn signal flasher in the Vette?

Could their possibly be a relay? Not having a wiring diagram I don't really know. But I would assume there is one to check.

I don't know if there is a separate flasher, but check the turn switch itself. You do notl have to pull the steering wheel -- Use a test light on the wires to the steering column.

Flashers

Doc here,

Yes, And Corvette put it all the way up and to the left on the fuse panel for your convenience..



You almost need to pull the seat out to get to it unless you can get an arm up there, twist your body sideways, while looking in the other direction, feel around for it and pull and replace it..the EASY one (on the bottom) is your 4 ways,,figures..

Most common , they fall out of the fuse block or don't make connection well, but If your going to all the trouble to get there..put a new one in! They are about $1.98 at Wally mart...

If that does not get it post back, we'll take a look at the column wiring..

Doc

The emergency flashers work, however, the turn signals do not work at all. No light, nothing. I've changed a flasher, but it must be the emergency flasher. I can't find the additional turn signal flasher.

Doc here,

Look Catti~corner ON the fuse panel..the flashers should be top left...the emerg. Flashers should be bottom right...

If that dosn't cure the problem, it is probably inside the steering column or at the bottom plug..frayed or broken wire or plug not seated..signal actuator arm broken, Do the brake lights still work?

Okay, then I have already replaced the flasher for the turn signals. You're right, it was tough to reach and see what you were doing. The flashers still do not work. The brake lights work. In fact, all other lights work fine.

flashers

Doc here,

OK, If your sure the fuse is good...(check them all..may not be marked..) This is the diagram for your car...



Sorry for the cruddy photo, you will have to donload it and print it out enlarged to read it better..

The wire feeding power to the flasher according to GM AND on to the directional switch will be one of the following colors..

Dark blue
or
Pink/Black
or
Pink/white

Determine which color yours is ...With a Volt ohm meter DMM or test light, turn the key on, and test that wire (or each side of the flasher socket if you can't find the wire) If you have Power on one side...

Isolate the Purple wire out of the flasher, It goes to the directional switch on the column..(you can probably pick it up there at the column plug)

If you have power there...

The problem can only exist between the column plug and the switch in the column OR the ribbon wire between..

You'll need to pull the steering wheel expose the signal switch and ohm out the harness through the column to the bottom plug..there you should find an "Open" that needs repair...

Doc

Turn Signal

I've tested each location and confirmed I have power up to the column wiring connector so the "open" must be in the column wire or the turn switch. I suspect the switch. I removed the steering wheel, but I am having trouble with the hub piece. I have a standard column (not tilt/telescopic). Anything else I need to remove the hub piece?

I've checked all of the wiring and it seems as if the problem is with the turn switch. I have the wheel off, but I am having problems removing the hub piece. Any idea's on this? Thanks for your help.

Hub

Doc here,

If it's a standard wheel there should be no magic to it at all..just lift it out..

But if it's different than tilt, or standard, you need to compress the hub (push it down) and remove the "C" ring lock or circlip.. to remove it..

See if the hub will compress, if so then that's how you need to go..make a compression tool from a bar and two bolts, drill the center the size of the steering shaft and tighten the nut down, until you can slip the "C" ring out..

Or you can buy the tool from General Misery for about a mortgage payment...LOL.

My manual say's non Tilts won't be this way, but who knows? My 80 vette isn't supposed to have a computer in it or enamel paint..but it does...

Doc

I may be wrong but ...

I think the turn signal flasher relay is on the passenger side of the car, tucked up behind the dashboard. It is on my 75 vette. Hope this helps.

I found the other turn signal flasher. It was located under the dash on the passenger side of the car. It was hooked in a clip on the far right side under the dash. Changed it and the turn signals work great now. Thanks for all your help and suggestions!
