      There is a sensor that screws in the corner of the cylinder head back by the firewall on the driver side. What is this sensor that has one green wire on it and looks like it was made on it.

      Several possibilities; faulty coolant temperature switch, faulty temperature switch connection or wiring. The difference (generally) between water and coolant - is the term 'coolant' usually refers to the anti-freeze and water mixture in the cooling system. Typically ethylene glycol-based - it's job is to; 1) raise the boiling point sufficiently so the engine does not overheat, 2) remove heat from the radiator and 3) provide corrosion-resistance and protection inside the cooling system.

      This could be the disc brake wear warning indicators telling you it is time to replace your brake pads, If you do need brake pads keep in mind that most brake rotors ought to be replaced at the same time. If the brake pads are more worn on one side of your car it indicates a problem with your calipers.

      how was the alternator checked ? did you bring it to an auto parts store?
      3/1/2011 Angie
      Yes I took my car to the auto parts store and asked them if they might know why my lights are dim. The man came out with a scanner to check if it was my alternator or my battery. It checked out that I needed a new battery. I bought a new battery and they are still dim. Do you have any idea what this could be?

      FYI another thing that makes the lights dim . You see it all the time . A car with one bright light and one dim . Most times the dim light has a bad ground .

      There are kits out there to polish and improve the clarity but the real fix is buy new ones. they are not difficult to replace.

      I've had success with a clear plastic polish or compound by Meguiar's - cost around $4.00 - $5.00 at local auto part store. It goes on similar to wax - just apply using damp clean cloth, and buff clean. This will cut and remove the haze on the headlamp lenses.
      House Call Auto is correct - if this treatment does not work - then the only other option is new headlamp assemblies.

      I have a 2000 Grand Am GT1 and I replaced both my headlights, it's not difficult at all. I wouldn't spend extra money on the cleaner when in the long run you're going to have to change them anyway.

      It could be evaporator condensation. If its leaking in the passenger compartment, the drain tube is clogged.

      If this has occured gradually then you have bad struts in rear or too much weight.

      1.Pull your Pontiac Grand Prix to within 25 feet of a flat wall, like a garage door. Park the vehicle on a flat, level surface.

      2. Measure from the ground up 4 feet on your flat wall and using the masking tape, place a horizontal line across the wall. The horizontal line should be a little wider than the width of your Pontiac Grand Prix.

      3. Locate the center of your vehicle bumper and transfer that position to the horizontal masking tape line on the wall. Using the masking tape, make a vertical line across the horizontal line in the position that represents the center of your vehicle's bumper.

      4. Measure from the center of your vehicle's bumper to the center point of each headlight. Transfer those measurements to the horizontal masking tape line in the same manner that you transferred the center point in Step 3.

      5. Open the hood of your Grand Prix. Locate the adjustment screws on each headlight. The vertical adjustment screw will be on the top of the headlight and the horizontal adjustment screw will be on the lower outside edge of the headlight.

      6. Turn the headlights on and set them so the low beams are showing. Using a screwdriver, adjust the screws until both headlights are centered on the horizontal and vertical center points you created with the masking tape. When they are centered, turn the vertical adjustment screw until both headlights are showing the top of the light, across the horizontal tape line.

      7. Turn off the headlights. Close the hood of your vehicle and remove the masking tape from the wall.
