Having problems with your 2002 Mercury Mountaineer ?
Left blinker is fast front blinker light working left rear blinker light not working.
When a turn signal bulb is blinking fast, it is an indicator that a bulb is bad in the system. Replace the left rear turn signal bulb, then see if the left front blinker has gone back to normal. This is most likely your problem. Let me know if it is still a problem and i will help you fix it. Good luck
