Question Details

I’m trying to replace the front signal light. I got the bulb and took out the old bulb and put it back in. When I tried the turn signal, it didn’t work. So I tried switching the other signal turning holder from the right side to the left side to see if it was something else. It’s still not working. How do I get it back on and working with the new bulb?

There is a chance the SAM module may be defective.

As first step I would check the fuses.

Have you done that?

I've got exactly the same issue including headlights being on all the time, fuel level reading zero and remote locking not working unless you're very close to the car.
I've checked fuses everywhere but there seems to be nothing obvious. Which SAM unit would this be linked to?

My guess is that it is the front SAM module. But that's only a best guess. You need to read the codes to be certain.
