I have a 1999 Ford Taurus. After a rain storm when I had left my driver window open an inch and a half. I used my headlights normally by using the on/off knob. When I had gotten home, I turned the headlight knob off and the lights stayed on. Also now my dash light doesn't work. I had to pull the 10 amp fuses to turn the headlights off. I removed the headlight on/off switch to see if the headlights would go off when I pulled both plug ins. They stayed on. Help me with this strange please....

Dead battery. You must have left the headlights on or something. Sometimes when you turn your lights on from the passenger side without opening the driver-side door, the headlights may not go out automatically. Been there, done that!

You replace the headlight assembly - they run around $75-$100 online for each side.
Sometimes you can refurbish them. There are Youtube videos showing the process.

If you have the owner's manual, check the chart showing which fuse is for the dash lights and that alarm. Try replacing that/those fuse(s) to see if you're back in working order. (Not sure where your fuse panel would be, but try the area under the dashboard on the driver's side.)

I suspect the cooler line at the radiator. the half shaft seal is 2 feet away from the wheel.

remove spark plugs and high tension cords/ remove the valve cover bolts using socket wrench/ use screw driver to lift up the valve cover/ clean the lid/ put a new gasket and put silicone gasket sealant on the edge of half moon rubber gasket to avoid leak/ tighten the bolts/ put the plugs and wire back...

I would have to think that it is in the window motor itself instead of the fuse. If the fuse was bad the window would not work at all. The mechanism that controls the window in the door is where I would start.

1. Make sure headlamp is off and open hood.
2. Taurus model years 1990-1999: you must remove the whole headlamp to replace the bulb. Not a horrible task. Just annoying.
3. Facing the driver's side headlamp, and looking at the headlamp itself, at clock positions 8, 11 and 1 are the headlight housing screws. They all look the same. Using a 10mm socket wrench, remove these 3 screws and set them aside.
4. Just to the right of the "11 o'clock" housing screw is a bolt (same hexagonal 10mm sized top as the housing screws). This just needs a few turns to loosen it.
5. Gently pull the whole headlight forward. Now you can get at the bulb.
6. Disconnect the electrical connector from the bulb. Now the headlamp is free to work with. Remove the bulb, replace with a new bulb, make sure the bulb housing cylinder is in place and reconnect the electical.
7. Place headlamp back into position. Line up screw holes. Tighten the bolt. Replace housing screws and tighten.
8. Passenger side headlamp is mirror image of driver's side. Screws at 11, 1 and 4 o'clock positions. Bolt should be to the left of the "1 o'clock" housing screw.

You most likely need a window regulator.

Get door stop, and pry the window fram back from the car. When you have it about 2 and a half inches open, take a metal/wooden rod and use it to open the handle. Works great, just be careful not to go too far.

First check the power window fuse,
1. Remove the door panel for the affected window.
2. Locate and remove the bolts holding the regulator to the door; it is likely you will have to manually lower the window in order to access the bolts.
3. Remove the old regulator, disconnect all wiring and check the wiring , replace the old regulator with a new one if defective.
4. Tighten the bolts holding the new regulator and reinstall the moisture barrier. Make sure all the wires are put back in the door before closing the door panel.
5. Engage the power window switch and the new regulator should work unimpeded.
