I have a 2004 ford freestar the dash light light came on for the master light switch now i have no lights at all is this just a fuse.

Check out your relays

More than likely a key problem. Dont mess with any fuses. A bad keywhen turned wont make any noise. If you have a 2nd key please try that first. If that is your only key consult a locksmith to see if they can program another key. Dont throw away a bad key it may be able to be reused. Good luck.

Check the electrical brake switch at the brake pedal and or hand brake. This could be damaged and not allowing the switch to spring back to the "contact open" position.

Look in ur 2004 freestar book and find the fuse it should be #9 (PATS FUSE)under the driver dash. Take the fuse out the lil red light on dash will not light anymore and ur van will start and keep the fuse out.

Not a fuse

What Fault Code do you have (air bag light)

You have a bulb burned out in your dash, needs a mechanic with the right knowledge to replace it, the are in an intergrated circuit board that runs all lights in the dash.

I have the same Question .....WHERE is the front blower relay located? Not the resistor or the speed controller.....but the front blower relay!

I'm assuming all of the brake lights are on? If so there is a brake light switch located way up under the dash that hits on the arm for your brake pedal. If this is not "closed" when the pedal is up (not depressed), your brake lights will stay on. It is adjustable.

check for loose wire behind the alternator when the light are fading our running on the battery only the alternator ir not charging get that check as soon as you can the frestar gonna stall soon thanks pierre
