I posted a couple weeks ago about my blinker problem, but I reached another obstacle.
Basically, I have an 84 Corvette and I just got done changing the entire interior carpet. After all was said and done, I go to drive the car around, and thats when I noticed that the right hand turn signal didn't work. The lights would glow orange but not blink. Many recommended that it was a burned out bulb. Today, I took the bulbs out and switched them with the left hand side bulbs, and again the same result, so the left hand turn signal worked and the right hand signal still didn't. So, bulbs are in fine working order. However, I'm not sure what I touched or did in the process, but this made it so the green arrow that normally flashes for a right hand turn instead is constantly illuminated when the headlights are on, no matter what. If I don't have the headlights on, the right green arrow won't show no matter what.
So now I am left with idea that while changing the carpet either under the passenger or driver side, which required removing the panels there, that I touched, disconnected, or broke a wire that connects to the right blinker.
Does anyone know what to look for, perhaps a particular wire, or just have any other idea on how to fix this in general? Thank you very much!

 

Did you replace the turn signal relay? The metal cylinder that makes the blinking noise and controls the turnsignal operation. Sound like this is fried. GC

 

The car still makes the blinking noise. It sounds like that is coming from under the passenger side dash. How much does that cost? Easy fix?

 

Easy fix just a PITA to get too the part is less than 4 dollars. Normally the indicators wont flash or stay lit in the on position without blinking. Give it a whirl its potentially a cheap fix. Just and educated guess here. Next I would look to the turn signal switch in the column. Good luck GC

 

Check the ground for that side. Sounds like a bad connection.

 

The fact that you hear the turn signal flasher means that it is working. Does the right side brake light work? Do the 4-way flashers work (all lights flash)? If so, the then I would suspect a ground to the turn signal switch or the switch itself. Another possibility is that a connector somewhere where you were working came loose.

 

At the bottom of the steering column is a connector, you will no doubt find a bad connection there, i believe it is the white wire ( had same problem on my 87 )

 

That's great I will take a look! It's always something else with this car. But I will not rest until it's done!

 

Changing the carpet is merely a coincidence and has nothing to do with your turn signal problem! The turn signal flasher works on lamp current, low current, slow or no flashing, high current rapid flashing. Your bulbs are dim on the no flashing side because of low bulb current. Most likely you have a poor ground connection on one or more turn signal lamps and you can find this by measuring the voltage between the socket base which is grounded and the negative terminal on the battery with the turn signal moved to that side and the ign in run (engine not running because it isn't necessary). Normally the socket base with the lamps on should have less than 0.1 volts on it with respect to the neg battery terminal (ground). You will probably find several volts on the socket base causing too low a voltage across the turn signal filament to operate the flasher. There is a black wire from each lamp socket base that goes to a splice in the wiring harness and then to a connector and then to a lug that a screw goes through and into the frame (ground). I am sure you will find the screw rusted, corroded which causes a poor electrical connection (resistance) and is responsible for the socket base being above ground by several volts.
I explained this in your last post, but you just don't want to believe me. You can even not own a voltmeter and use a well grounded wire and touch it to the socket or to the ground wire and observe if flashing starts up. Good luck.

 

I agree with JFB and have two cents to add (no, I am not going to say you are low on blinker fluid). IF, big if, the 84 Vette uses the old style bulbs that push and twist into a copper/brass socket then even corrosion inside on of those sockets could cause a lack of ground and the issues you are facing. Just a thought, hope it helps.

 

I don't mean to sound unintelligent, but I really don't know what all this talk about ground is. When you say ground wire, what does that mean, how do I check, what does it look like? I'm a newbie at all this. Reading that long post confuses me and sounds very complicated.

 

Amminich has some very good advice about the inside condition of the turn signal lamp socket!!! Look inside the lamp sockets, also, I recall that a poster had some corrosion on the two contacts in the socket that make connection to the tips of the bulb. What my long post means is that the black wire from the grounds on the turn signal sockets has a poor ground connection to the frame due to rust or corrosion where the screw goes into the frame.
Since the rear lamps on both sides have the same ground, and the front lamps have separate grounds, I would look at the ground connection on the right front turn signal lamps. This ground connection is a black wire right behind the turn signal lamps and just above the right side horn. Remove the screw that grounds this wire and clean the screw and screw hole and replace the screw.

 

Thank you! I will dissect this problem using your advice and post results.
