Brake Light/turn signal problem...

1966 289 COUPE GT / T5 / AFTERMARKET Air-Conditioning .... I put in a sequential taillight kit and have been running it for at least 6 months.. car runs beautifully and has had no issues what-so-ever until now.. left turn signal works as intended however the right turn signal doesn't work and the car wants to quit on me (I'm assuming some type of short). The brake lights I noticed were not working one night and was testing them out.. when i stepped on the pedal as hard as i could they started working again, but eventually went out again.. now (with the car off) I can hear a very faint pulsating sound when I hit the right signal... I need your thoughts ASAP considering this IS a daily driver car.. I would need some guidance for I am no electrician .. thanks in advance

also i had just put my AC back in!! ( i think this is where the problem lies)

POSSIBLE chance your turn signal switch might be bad now since it does access the brake light and turn signals. That's the only thing I can think of right now. Fuses?

i didnt even think about those dern things.. just checked and there are a couple blown.. but I'm not sure if those are involving the signals at all..

are you talking about the little round thing over by the emergency flashers? or the actual sequential thing that came with the kit?

and fyi i just tried again and pressed the pedal down to the floor.. brake lights kind of worked for a few seconds and then just flickered.. would it have any thing to do with that brake pedal switch?

That could be an issue. If it's original, it could be near it's death date. Your turn signal switch is behind the steering wheel. Like I said, it does control both of them. Weird, huh? Maybe the brake switch might need to be replaced. Kind of sounds like the brake switch if you have to like slam on it to work properly. If the fuses are good now and still has the problem, it's one or the other or could be both. Check the wiring as well. Maybe you have something loose now. I did read that some people had to buy a new flasher for the sequential mod as well.

just for giggles.. i had put in the old signal and bulbs.. does the same exact thing.. I checked all the wiring and it checks out..

Next step is to change the sensors.. I'll send an update when I'm done..

If anyone has any other advice (I wouldn't assume it would be anything else, but like I said I'm no electrician) it would be appreciated..

The brake light switch applies power to the turn signal switch for the rear turn signals, so being it has sequential tail lights the left side is separate from the right side, now since the left one works, either there is a problem with the turn signal switch or the sequencer for the right side. Good Luck.

even if i have disconnected the sequencer all together would that affect the brake light to the right side? I have replaced it with the originals and still get the same problem.. I'm going to say that it's most likely the signal switch O__o unfortunately .. this weekend is going to be fun.. gonna order one tomorrow and install it next weekend.. if anyone had any other suggestions that would be appreciated greatly!!!

It could be as simple as a loose connection, a sequencer needs to sense power for the turn signal and/or brake operation (this can be done by sensing both sides at the same time and also a separate wire from the brake switch to let it know if the pedal is pressed), needs battery power for the extra bulbs unless they are leds. If you have a VOM or DVM you could check to see if these are present at the sequencer. Good Luck.

There is a plastic connector under the dash that the wires from the turn signal go to. I had the same issues with the turn signals and brake lite on my 66. The wire going into that connector was loose. It appears to be connected but there was not a solid connection. Same issue some times I had left turn signal some times right and some times neither. pull the wire harness out should be enough slack. Put key on accessory and play with the wire into and out of the connector and see if the turn signal works.

switched out the brake light switch and the turn signal switch and now i have the left brake light.. no turn signal nor brake light on the right side.. and i checked all the wires going into the plastic connector piece and they check out.. i'm not receiving any power through the (orange and blue) wire going to the right tail light.. however my running lights work.. i turn the right signal on and the dash lights up as normal.. as for the left i get a faint dim dash light indicator and every once and a while i get a really slow signal.. however the light still does not light up.. i'm so frustrated at this problem.. please help

Check the plug that connected from the dash to the engine bay, its on the firewall, mine came loose and made that noise, just a possibility.
