I got a 2002 ford taurus and when i go to turn my headlights on the interior light dont work and the blinkers light up but they do blink when im turning, i was what it could be thats causing that thank you

Many turn signal lamps will have multiple bulbs in them. If "one" of the bulbs is faulty, the interior lamp or lamps will come on, indicating a bad bulb. You will need to turn on your left blinker and view the bulb and make sure all bulbs appear to be blinking on front and rear of the car, then repeat with the right blinker. If you find one that doesn't appear to look right or blinks faster slower or dimmer, then replace the bulbs in that turn signal. The interior light may begin working properly when you replace the "shorted" bulb for the turn signals. If it does not, check the fuses to make sure the "shorted" bulb didn't damage your fuse for the interior lights.
