Right blinker (front and back) not blinking/solid when brake pressed
Just bought the car and originally the front right blinker light didn't work at all so I replaced it and it seems to be fine most of the time... the issues with the front right in specific may be a short/other issue, cuz sometimes it won't turn on at all.
The main issue I have now is that when I have the right blinker on, the brake light seems to 'override' the blinker light. So what happens is when I turn the right blinker on, it works fine until I start to press the brake, then the blinker stops ticking on the dash and stays solid green and the lights stay solid on just like the brake lights on the left side do. This issue does not happen to the left blinkers.
Could this be a malfunctioning multi-switch on the steering wheel? I was thinking this because my low beams also don't work properly in manual mode. Sometimes the headlights go up without lights, and sometimes the lights turn on without the headlights going up. Brights work fine. Twilight sentinel works fine (which is how I have to use them since it doesn't work manually)
Thanks! Love my new vette either way, but would love it more if it was legal to drive
It does sound like a problem with the multi function switch, but not exactly. If the MFS wasn't disconnecting the brake switch from the right lights then when you signal right all 4 tail lights would be flashing.
Does the car have any light modifications like LED lights or Euro tail lights?
Often issues with the blinkers are due to a problem with the 4 way Hazard switch in the dash. Try pressing the 4 way hazard switch multiple times and see if it changes anything. If the issue goes away the hazard switch is the problem and needs to be replaced. It can also be bypassed with a hyperflash harness which is easier to install than replacing the hazard switch. It will also allow you to run LED bulbs in the your tail lights and front blinkers if you want.
So I just went out to check again... The front right light also doesn't pulse at all. The car was in park with ebrake off. The left blinker pulsed file but right one just stayed on low with no pulsing aka no blinking. I am probably going to replace the stock so I can fix the manual headlights. I'm wondering if any of this could also be caused by a short or bad grounds or something else?
I replaced the blinker switch with one I bought on ebay and the issue is exactly the same as before. The blinker switch was not the cause of the issue.
What is the blinker switch, the MFS or the hazard switch?
The front light sounds like a ground issue. I'm not sure exactly how the brakes are over riding the rear signals. If the MFS connected the brake and signal together then the brake would over ride the signal but the signal would also power the opposite side brake light.
The rear signal and brake lights are always brighter than the tail lights and always equal on both sides?
The center brake lights works like it should at all times?

No LED bulbs in the car?
Honestly I can't tell if the bulbs are led or hid or halogen. I know the front right blinker is halogen cuz the first thing I did was try to replace it. I don't think any of it is HID or LED though. I admit I keep forgetting to check these questions, sorry for that.
When you say the front light sounds like a ground issue, do you mean the blinker or headlights? Either way how can I fix that? I have a multimeter I just am not very familiar with what I am trying to check yet. Thank you so much for the help!
Okay so I took a closer look today, when the right blinker is on, the center brake light also blinks, which I assume is incorrect. When the left blinker is on the center brake light does not blink.
Yes, that is incorrect. It's starting to sound like the ground wire for the rear lights is bad.
It does also sound like the MFS except for one thing. When the right signal is on, the wires going to the center brake light and the left brake/signal lights should be connected together which would mean that if the MFS was signal powering the center brake light to make it flash then it would also be signal powering the left brake/signal lights and making them flash.

Okay I found the culprit.
The previous owner spliced in that black wire (previous photo) to the green rear light wire that is under the tape, so when the center light was on (brakes on), it would make the right light solid and when the right blinker was on, it would make the center light blink too. I disconnected it and now the blinkers work fine, however, the brake lights do not work at all except on the center light. I also have no idea where the black wire is actually supposed to go to... It comes out of the center light and I believe it is factory but idk where it is originally cut from.
So yes now the issue is the right and left lights do not light up to their higher brightness like they should when you press the brake.
Also note I tried connecting that black wire to the black wire on the headlight instead of the green one and it just blew a fuse lol, so that's not the solution. I think my hazard switch is fine too but I have no idea actually, maybe it is the cause? I've heard some people complain about it causing issues.
The hazard switch has a contact that disconnects the left and right brake lights from the brake light switch and connects them to the flasher instead. So, I would now suspect the hazard switch.
Is the black wire spliced again at the center brake light?
The black wire went from the center light (I think it was connected there by factory, but I couldn't see inside the bumper well, just felt around with my hand), and whatever the other end was connected to was cut by the previous owner and connected to the green wire by the previous owner. I'm not sure where that black wire should be connected to but it surely isn't supposed to be just hanging there by ittself unconnected 😂
I also already bought a new hazard switch, should arrive in a week and I will install it to see if that fixes the issue.
Okay so I replaced the hazard switch and it fixed the issue however now both of my right and left blinkers blink rapidly lol. One problem into another. I did notice that 2 of the prongs inside of the old hazard switch were twisted so that they probably didn't make any connection, so I'm almost wondering if the previous owner did that on purpose to stop it from rapidly blinking for some reason? idk. I looked it up and the rapid blinking is supposed to be caused be lower power draw/a bulb going out, but I think all of my bulbs in the car are working and halogen, except possibly the headlights. It might be HID or LED I am not sure actually, those are like the one I haven't checked I think.
