My blinkers don't always work,it seems when the car is moving they work better than when at a stop. Is this an alternator problem or something else? I've asked around and it seems to stump people.(of course they don't a chevelle with 'quirks') Any ideas would be great.

Not an electrial "specialist" here, but, have you checked out your turn signal "components" in the steering column? Could be that the little brass colored metal pieces that touch when you activate your turn signal could be either corroded and/or need replacing. You'll need to take the steering wheel horn cover off, a steering wheel remover tool, and (not sure what it's called) that tool to remove that metal "sprocket" looking piece in the middle of the steering shaft to get to the turn signal things. Sorry for the lack of better words
:D Hope you fix your problem and good luck!

Not sure what you mean be not working. Do they stop blinking and just remain lit? Do the headlights dim down at the stop sign when this occurs?

No I haven't checked the components in the steering colom, never taken the wheel off. The blinkers will work 1-2 times at a stop then will stay lit. While driving the blinkers work fine eg: slowing down but not stopping to make a turn. I'm thinking this is related to my horn not working also (it shorted out in the middle of the night 4 years ago. Just started blaring at 11pm at night, weirdest freakin thing!!- So I just pulled wires till it stopped. mechanic says the part I need has to do with the steering wheel & the part is not to be found..) Does :confused: this help?

Not sure what your mechanic is referring to. If this is for a 70, all parts are available to rebuild a steering column.
I understand now that the signals stop flashing when you stop. What happens if you put the car in neutral and rev the engine some. Do they start working again? My other question. Do the headlights dim at a stop sign and get visibly brighter as you take off again?
BTW
Problem is not related to the horn not working.

Yes, now that you mention it the headlights do dim when at a stop, then get brighter when the gas pedal is pushed. I haven't tryed revving the engine in neutral & then checking the blinkers, I'll deffinately give it a try. Car is being stored now
& I'll ask mechanic about the horn part. Is it a pia to take apart the steering colum?

If the signals start behaving themselves again check or try the following.
1, Even if the signals are not flashing check to see that all the bulbs are lighting up. A bad directional bulb, either front or rear can make the signals stop flashing.
2, Replace the turn signal flasher can. This is the one under the dash and not the one in the fuse block. It is located under the dash between the steering column and radio. If it is trying to work a little you can usually locate it by listening for it. Buy a cheap one from the auto parts store. Don’t buy a heavy duty one. It won’t work well. A cheap one is around $3.00 and takes 5 minutes to install.
3, Check or have someone check the output of the alternator. This is the large red wire on the alternator rear. It should measure around 14.5 volts with the car running. Suspect that it’s close to that when the engine RPM is high enough but drops down when the car idles. If that’s what’s occurring, change the regulator. Regulator is located next to the radiator on the left hand side. Buy a solid state unit. At Auto Zone ask for a Wells part number VR715. Around $11.00. Disconnect the battery before installing this. About a 15 minute job.
4, As Alex mentioned there are a couple of tools to get into the top of the steering column. One to remove the steering wheel and one to remove the GM lock plate below the steering wheel. Each is around $8.00 from an auto parts store. However, the problem might be the horn relay itself. I’d try reconnecting the wires to it one more time. See if the horn still blows. This time disconnect only the small black wire. This wire comes from the horn button. If the horn still is making noise, there’s a good chance that the problem is the horn relay.

Thanks for the help John, I'll try what you suggested & let you know how I make out.
I do know that all the bulbs are working.
If the horn relay is junk, is this a piece that can be found?

As always, check the ground wires, When I built my streetrod and put ALL NEW wiring in. I was driving happly down the road when the turn signals and lights went south, After about a week of (well you know) saying things that would make a sailor blush, someone suggested checking the all the wiring ground after that I found the grd in the headlights...... Well the grd wire was barely loose, but enough to cause grief. But, installing a new turn signal cam is a smart thing. Even if your not sure when it was replaced. or if it ever was.

1970 Chevelle 427/4spd SS
1950 Chevy "streetrod" pickup (built)
1972 VW Super beetle
1974 VW super beetle
1988 GMC 4x4 restored SB
1976 Ford 4x4 SB rust bucket
the list goes on........

I know nothing about electrical stuff so sorry if this sounds like a typical "girl question" but where are the grounds?
Under the dash, or under the hood or.... If replacing the signal cam doesn't work (that would be too easy)I will try to tackle the wiring components (should be a shockingly good time
)
I'm sure nothing has ever been done to the signal cam or wiring for that matter,as I've had the car for, well, many years.

Sometime the bulbs can get corroded, especially if they have been in the car a longtime,(ie. turn lamps, and brake lights, marker lights) you may need to pull them and check each one.. The wiring for the front runs along the top of the inner fenders, the rear wiring can either be (run) thru the trunk or underneath the car, you might give it the once over to make sure nothing looks (chaffed) or corroded, broken, sounds like alot of work but at least you well have an idea of the general wiring. before you head under the dash, that can be rather scary...

Wiring can either be one of two things Ground, and everything else. That doesn't help. Good Luck


It's a Gal thing too!!!

I had a similar problem with mine...Left blinker worked fine during the day however at night when the tailights were on the left blinker would either blink very slow or remain lit. Problem was a poor ground contact on the rear bulb. Bulb grounds through connector to tail lamp housing contact. Simply reseating the connector took care of the problem.

My problem has got to be the same thing. If that doesn't fix it then I'll replace the turn signal cam.
Thanks for your input
