Both filaments light in the 4 each 3057 bulbs when the key is turned on.

When you use the left turn signal the flasher clicks normally and the upper LED brake bar flashes. The left front yellow lights (front and side ) flash alternately.

When you use the right turn signal the flasher clicks rapidly and the upper LED brake bar flashes. The right front yellow lights (front and side ) flash alternately.

The filaments in the bulbs and the sockets look OK. Disconnected and reconnected the battery with no change. Perhaps a ground or turn signal switch?

Checked the 4 way flashers. They operate normally.

Most likely has a bad turn signal switch.
