My turn signals are pretty messed up. If I am idling and turn them on (like sitting at a stopsign), they try and try and try.. then flick.. then try and try.. and stay off.. its like the blinkers are trying to get enough momentum to turn on, and if they do, they turn on briefly, but most of the time they wont blink. It is just fine at higher speeds, but at idle, its a problem.. Any ideas?? (My voltage readings from the battery and alternator are just fine.. so I dont think it is either of those).

sorry I can't help, but maybe you will find someone here who can. Here's a bump for ya. :thumbs:

 

Your '92 should have a small caninster shaped unit located under the instrument panel to the left of the steering column. If the flasher unit is functioning properly, you should hear a clicking sound during the blinking operation. Since you have an intermitent problem, your fuse should be OK. You may have a faulty flasher unit, a faulty switch, or a loose connection.

 

The "clicker" clicks every time the blinker flashes (say that 10 times fast!!), it is just real hard for the blinker to flash.

 

Sounds like you located the flasher canister, and that it "clicks" when your blinker light flashes. That's good. Now you have to find out why it doesn't flash at all times when you activate the switch. Either you have a faulty canister, switch, or a poor connection. The easiest start on a fix would be to purchase a new canister. I don't mind spending your money.

 

How is your voltage at idle? If its working fine at higher speeds then I am thinking that with the alternator turning at higher speeds your voltage is high enough to make it blink. If it takes a higher voltage to make it blink at the normal speed then its probably the canister he is talking about putting a new one in. If your voltage at idle is ok that is.

 

The reason I dont susupect it is the voltage, is because the rest of my electrical system seems to be fine. I would expect that headlights would be a much bigger draw, and 1) they are steady and bright.. no fading, and 2) no matter how much other stuff is on (headlights, heater, radio, etc..) the blinker problem doesnt get worse, or better. BTW: have any idea how much one of these blinker canisters is??

$5.00, plus or minus a buck or two.......no biggie..........that's why it is recommended you start with the canister before you tear into the steering column switch.

Sweet.. something on the Vette I can afford!!! :D

 

On my 88, I have to take the top dash off to get to the flasher. I changed it while doing the heater core:)

 

Speculating here. Not sure if your model has the bimetalic strip design for turn signal flasher. Is the condition present for a left or right turn? If the condition is not dependent on left or right turns, condition present for either left or right turns, suspect the flasher unit.

Now, if only left or only right turns are involved, then I suspect loose bulb, connections etc.

On some designs, both front and rear bulbs must illuminate for flasher operation. When sufficient heat energy accumulates from both front and rear bulbs, heat will cause bimetalic strip to "trip", causes break in current, strip cools down, resets, connects power, start all over.

My recommendation should this occur, attempt to determine if a bulb is not illuminating. Jump out and check front and rear bulbs. If both front and rear bulbs are displaying correct illumination, suspect the bimetallic strip may not be functional. Again, this is a guess. If the bimetalic strip has not reached the correct temperature, it will not trip, or the bimetallic strip has somehow lost sensitivity. Your symptoms suggest a loose connection, not making contact when sitting still, making contact when in motion. Just a guess. Let us know. Always curious.

I have had loose bulbs, bad bulbs, bad connections, darn cars.
