My left turn light is blinking rapidly?

Hello,

The turn signals blink fast or hyper flashes typically due to a bunt out bulb.
So first you will need to check and see which bulb is burnt on the side it is blinking fast.
It can be helpful to compare the lights on the normal functioning side to the faulty side. This can help determine what is bunt.
There are small corner light that goes out on these vehicles and that leads to hyper flashing.

Here is a helpful guide:
