How do i check the lr turn lamp on the ford fusion?

If you're seeing the phrase check LR turn signal on your instrument panel then that is warning that the bulb has died out on your left rear turn signal. To test that this is actually the case go ahead and give your vehicle power and activate the turn signal. Now exit the vehicle and head to the rear. If you don't see a light then you have a problem. A replacement bulb is going to cost you between $5 and $15. You should purchase a long life bulb if it is available to you. If changing the bulb still does not fix the issue then you have wiring problem.
