The front turn signals are controlled by the front SAM, connector "C" wire #31 Pink/White.

With the key out of the ignition, test wire for 12v, making sure that it is a Pink/White wire or Pink.

If there is 12v, remove conn. C and check for corrosion.

Post back with results.

I think that I have to remove the passenger seat to reach the SAM
Because there is a black plastic cover to the right of the battery May be the SAM under it

First move the right front passenger seat all the way forward. Then flip down the right rear passenger seat.

Look in your owner's manual for instructions.
