My ESP OFF button doesn't work. Also, when the headlights are on, the ESP button doesn't light up. What could this be and how do I fix it?

Could be that the ESP Off button is dead, might be a bad connection, or possibly a local corrosion, any liquid spilled in there could cause that. Honestly no clue why its dead, probably needs to be taken apart to find that out. I would say that its a local problem, meaning its the button thats faulty, not ESP or anything else.

It could be that the contacts in the switch have a slight corrosion film on them. With the engine not running, work the toggle switch numerous times and then recheck operation.

yea, it has to be something with the button because ESP is still working great
