SOURCE: Ford 2003 Windstar Interior Floor Lights Stay On

to repair this problem you must remove floor lights from seats and check the circuit for either a short or a stuck switch use a multi tester this can get to be irritating as the short may be not directly behind switch could be along wiring that runs through car my suggestion if your not electrically proficient is take it to an electromechanic shop or simply unplug the light from socket to avoid draining the battery.

Your alternator should power everything when engine is running. Battery is only for start up. Test voltage with a multimeter when engine is running , should be 14V or more . Any less indicates low alternator output.

2003 Ford Mustang won't shift out of park


Could be the brake switch, or the shift lock solenoid.
Both components would need to be tested. And you may be able to shift out of park if you try before you turn the key switch to the on position.

Brake lights 65 mustang stopped working.I wondered can the issue be in steering column


On a "one brake light bulb per side" setup,the brake switch feeds 12v to the turn/hazard switch,and the switch will apply 12v to both when no turn signal activated,the right only when the left signal is on,the left only when the right signal is on,and none when the hazards are on.With this in mind,it IS possible that the turn signal switch or wiring is the issue.If you are still running the original switch,try removing the switch and cleaning/regreasing the contacts(or look for something obviously worn or broken).If the switch is bad-hey,you got almost 50 years out of it! I'll bet you won't get that much longevity out of anything built now!

1998 Ford Windstar Minivan: 1. I sometimes get an extended crank when trying to start engine after I've made a short trip. 2. My interior lights won't go out after I turn the engine off, so I...


YOU MAY HAVE A BAD DOOR AJAR SWITCH. HOWEVER, YO HAVE A TIMER THAT SHUTS OFF THE INTERIOR LIGHTS AFTER 300 MINUTES. IT'S CALLED A BATTERY SAVER FEATURE. TEST IT OUT.

THE EXTENDED CRANK MAY BE A CHECK VALVE IN THE FUEL PUMP IN THE TANK, ALLOWING PRESSURE TO DROP WHEN YOU TURN THE ENGINE OFF.
OR A BAD FUEL PRESSURE REGULATOR ON THE ENGIEN FUEL RAIL.

TRY THIS TEST, TURN KEY TO "ON" POSITION, WAIT 5 SECONDS, SHUT OFF KEY FOR 30 SECONDS. TURN KEY ON, WAIT 5 SECONDS, THEN START ENGINE. IF IT STARTS RIGHT UP, YOU ARE LOSING FUEL PRESSURE WITH ENGINE OFF.

THIS BUILDS UP PRESSURE IF IT DROPPED DURING SHUT DOWN.
REPORT TEST RESULTS.

PLEAE RATE, THANKS
