Front right inner turn signal stay on always even when car off

E2e5 +ve always even when car off

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.

Where are the main battery, the Auxiliary Battery and the front SAM?

Talal Al Hadidi

Under the passenger seat

Maj. Dundee

But your photo shows that nothing is there.

Talal Al Hadidi

Yes Sir
That what I found 😁

Maj. Dundee

Well then where is everything?

Is your truck right or left hand drive?

Maj. Dundee

Look under the right rear seat.

Talal Al Hadidi

It's left hand
I just open the passenger floor Nothing under it as in attachment
And I found rear SAM under rear right seat

Talal Al Hadidi

It was the right passenger seat where the battery were I looked
You mean the left seat ( driver seat ) ?

Thank you Sir for help me

Talal Al Hadidi

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

Maj. Dundee

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.
