Need help. All turn signals have always worked fine. Now the right rear signal won't. Here's what I've done so far (I'll adnmit up front I have No knowledge when it comes to electricity). I've replaced the bulbs from side to side, the bulbs work on the left turn, but the left turn bulbs will not work on the right. I put a meter on the sockets and the needle pulses when the turn signal is on. I then put in a bulb in the outside socket and put the meter on the inside socket, meter doesn't pulse. Removed light bulb from outside socket to inside socket, ran same test-- no pulse. Spliced into ground wire on outside turn signal and grounded wire to frame. still won't light. Spliced inside signal ground wire to outside signal ground wire and grounded that to the frame. Won't light and won't flash.

What am I not doing or doing wrong to solve this problem? Any help will be appreciated.

Do your taillights and brake lights work on that side? If not you may have break in the wire feeding that side. If they do then I would check to see if you front turn works either. If not the flasher unit under the dash is most likely bad. Little round silver thing should say 12v flasher on it. Real cheap to replace. In fact if you turn on the blinker to the effected side can you hear the flasher click as the reed relay kicks on and off? Check that first.

Yes, front blinker works. Tail and brake lights work on both sides. Will check flasher in A.M. Thanks for the reply.

there is no need to check your flasher.
your problem is in that back corner.

you have a coupe right?

answer back and i (or someone else will bet me to it) will tell you the 3 things to check for in the socket that is giveing you problems.

Sorry about that, it was a Formula, but was converted to a GT 5 yrs ago. I've never had light problems with it until recently. The conversion was done by Bob Steiger in his shop over a period of nearly a year. The kit was from Ace with some modifications, although I believe they were to engine installation.

After re-reading your post you have in a round about way answered many of the questions I was going to ask. So we have to do some more testing.

Will the right hand bulbs work in the left sockets?

Put all the bulbs back in and see if all of your hazard lights work.

try this same test on the other side, I really don’t know what you will get and I am curious for the results

at this point I am leaning towards bad contacts in the turn signal / hazard switch assembly or dirty / bad connectors in a plug somewhere and them allowing enough amps to flow to illuminate the bulb.

Unfortunately have been unable to do anything on car do to work hours.

The bulbs form the left turn sockets were put in the right turn sockets--the right turn signal does not blink. The right turn bulbs were put in the left turn sockets--they blink. All of the hazard lights work except for the right rear. I'll try the bulb swiitch on the left side in the A.M. and test it out.

If the turn signal switch was at fault why would the other turn signals work and only the right rear not? If it is at fault how difficult is it to chage or clean?

Thanks for continuing to help.

this is a quote from another thread that i helped a guy in spain convert his notchie tail lights to have an amber turn signal.
*****
The wiring…

The power runs this route…

Stop lights
fuse box
stop light switch
turn signal switch
rear bulbs

Turn signal
Fuse box
Flasher
Turn signal switch
Rear bulbs

The turn signal switch opens the stop light circuit to whichever side you are turning and closes the turn signal circuit to that side.

that explains how the notchies work, now when whoever did the GT conversion there are a few different ways that they could have powered the amber lights in the back, that will make a "normal" step by step test kinda difficult as we dont know the route of the added circuit.
they could have tapped in to the front turn signal wires.
they could have tapped in the the c500 (i believe ogre has a write up in his cave)
they could have really messed with the wires and did something like in this thread

HELP jazz, wheres your write up thread?
i think orge has one too but i cant go to the cave from my work computer.

I had this problem with an old volkswagen once and the answer was quite simple. Hope it works out for you as well. Since the turn signals were working before, I'm hoping the solution is in the socket contacts and not in the wiring. Take a dremel tool and clean the contacts inside of the socket that power the bulb. If that does not do it, you might want to look for a worn or cracked socket that could be causing the bad connection.

Curious, are the two turn signal lights you refer to wired up in parallel or series?

As stated in original posting "I have no knowledge when itcomes to electricity" but, what I can tell you is that there are three wires that come out of the outside turn signal socket...drk green, lt green and black. The inner turn signal socket has two wires...drk green and black. The drk green and the light green are siamesed in the same hole in the socket,the black is in a seperate hole., the drk green and the black each have their own seperate hole in the inner socket. I'm assuming the drk green runs between the sockets,the blacks go to ground and the light green is power, I don't know where the lit green goes to power..maybe the C500? It's unknown because it goes down between the rear clip and the frame. The wires for the inner turn signal go somewhere between the rear bumper and the trunk sheet metal.

I just added a note on how to fix rear socket grounds to my cave. See the lighbulb article. I'd been meaning to add it for a long time but with the recent spat of light problems I figured I'd better post it.

I only covered the ground because the "main" contacts in these sockets never seem to go bad. I think the grounds get loose mainly due to slight differences between lamps and people wiggling the lamps durring work on them. I've had to tweek most of my tail lamp sockets at one time or another after replacing a lamp in them.
