    All the exterior lights work just fine. It's only the left turn indicator that is on the instrument cluster - it doesn't blink or go on at all. Is that bulb replaceable inside the instrument cluster? If so, anyone know the type?

    thanks

    All the bulbs inside the cluster are replaceable. The best thing to do to verify if it is the bulb, is when you have the cluster out is to swap the bulb that is not working with one that is. If the bulb still doesn't light up, then you have a issue with the circuit board. If the bulb lights up, than it's the bulb.

    I don't know the type, but it's usually a micro bulb that your normal Auto Part store may or may not stock.

    Thanks. Will do that. I didn't have a small enough torx with me to take it apart today.
