Did you find out what the issue is?

Did you find out what the issue is? I am having the same odd problem. I start the car everything works, I keep the brake pedal pressed the left turn signal and brake light goes off I turn the signal right and then left it works again. I turn the signal right and leave it for five minutes or less and it stops working. I repeat and works again. It also works if I stop the car leave it for 3 minutes and start again ... is like this car has a mind of its own ...I am having the same problem on my rear left blinker. I replaced the bulb and problem still exists.
The blinker problem for my car only occurs when the headlights are on. Whats funny is that the blinker does actually blink for 3 times but then stops.
I can get the indicator light to go away and blinker functionality to return if I turn off the car and turn it back on.
I'm beginning to wonder if this is a faulty ground. This is just a guess from my research online but I am going to clean one of the grounds I can get to in the trunk and see how it goes.
Will post any positive results I have...
