I found that on my 2001 Windstar that there is no adjustment for the brakelight switch and that the problem was that the brake pedal return spring had a very slight amount of rust on it and needed lubrication(I prefer silicon spray) and that it also needed to be budged a bit with a screw driver.

More than likely it is your brake light switch out of adjustment. it is located under the dash on the brake pedel itself it is not breaking connection which it should be simple and you can fix it yourself and save yourself some money.

It's usually the brake pedal is sticking or you might just need to adjust the pin when you apply your brakes it makes those lights stays on. sometimes you can spray a wd-40 and it'll go away.. this pin is located on top of the brake pedal when you look underneath the steering wheel column or panel....hoped i helped you on this one...

The brake light switch may be either stuck or broken.

Get down in the driver's footwell, and follow the brake pedal arm up under the dash. Look for the switch (see link for a picture), see if the moving arm on it moves freely as the pedal is depressed. If not, try spraying some lube on it (WD-40 or the like) and working it to get it to move freely.

If the arm won't move freely, or the lights don't turn on even when you move the arm, the switch should be removed and replaced.

need to replace brk light switch and have battry and alternator tested

locate the switch on the bracket under neath the dash. it should have two wires coming infrom it. remove electrical connector, remove the clip and it should come out, reverse to install

All brake light switches are mounted either on the brake pedal itself or right next to it with some kind of "tab" on the brake pedal making the connection to the switch. On yours there may be some plastic decorative piece hiding it so remove the trim and you should see the switch.

look just above your brake pedal their is a pressure switch that closes when you step on the pedal. it has two wires of the back look at the plastic bushings($4.00 at dealer or the switch $15-$20 for parts)

My favorite trick is to leave the emergency brake handle up just a little bit - after I panic, I remember I had actually used the e-brake when I had the van jacked up. ;)

The brake lights are triggered by an actuator that is mounted in front of the brake pedal arm. Check the wiring connection to the switch. You can remove the wire connector and jump the wires inside it. If the lights work when the wires are jumped, the switch is bad.

It is on the steering column, but those rarely go bad. In fact, I have never had to replace one. Almost always it is because you have no brake lights. Possibly a bad brake light switch.

remove plastic crowl above brake pedal unplug switch remove, replace switch

Another Answer: The "AIS" (Automatic Idle control) is a step motor controlling a valve that bypasses the throttle valve or Throttle Body butterfly. At some point in time, the valve starts to fail and do not work properly, causing erratic or high idle speeds. Sometimes it can be cleaned, but frequently signals a worn mechanism and it is better to replace it, it should not be expensive. But check that one before purchasing the replacement.
