Just a suggestion, remove the light assembly, remove one bulb, blow air into the unit, see where the air leaks out, seal it with Goop. Quick and easy.

SOURCE: 2007 mercedes s550 turn key nothing happen new

Hi,

Do you have another key?

If yes, try with another key.

If the same problem persists with the new key, its unlikely to be a key issue. The starter system is fairly complex & needs diagnosing on a diagnostic tool such as Mercedes STAR diagnosis.

The EIS (Electronic Ignition Switch) reads the key information & sends a signal to the engine ECU to start (assuming it recognizes the correct key), the ECU then sends a signal to the starter to start the engine. The problem could be anywhere in between these components.

The EIS is a fairly common part for failure but this needs to be checked for fault codes & actual value readings to check the status of the switch.

I would take it back to the dealer for them to investigate as soon as possible as there is a chance it could fail completely leaving you in a stranded situation.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

SOURCE: scratched headlight lens that's leaking

Personally, I believe its not very difficult to replace if your a bit hands on. Looking at a Toyota Camry parts manual there are two to three bolts that hold the assembly in. You will need to remove the bumper in order to get at the lower bolt easily. However, you might be able to squeeze a socket in the location in order to loosen the bolt without removing the bumper. (though I wouldnt recommend)

Outside of removing it and reinstalling, the cost associated with the headlamp assembly is about 200 to 250 for an OEM part online. Now, if you are not going to install it and have a mechanic install it will cost you approximately 60- 100 dollars an hour. I would estimate they would book 2 to 4 hours. This means the total cost with parts would probably be around 370 to 650. All depending on the cost per hour and the booked hours. If you are a bit mechanically inclined and have a few tools you should be able to do it on your own. Also, do not count out buying a used headlight assembly from a local salvage yard.

SOURCE: I have moisture inside my

{: ) Some exterior lamps, such as cornering, turn signal, backup, headlamps or tail lamps may exhibit very small droplets of water, a fine mist or white fog (condensation) on the inside of the lamp lens. This may be more noticeable on lamps with "multi-lens" designs and may be normal during certain weather conditions. Condensation occurs when the air inside the lamp assembly, through atmospheric changes, reaches the "dew point". When this takes place, the moisture in the air within the lamp assembly condenses, creating a fine mist or white fog on the inside surface of the lamp lens.
Most exterior lamps on General Motors vehicles use a vented design and feature a replaceable bulb assembly. They are designed to remove any accumulated moisture vapor by expelling it through a vent system. The vent system operates at all times, however, it is most effective when the lamps are ON or when the vehicle is in motion. Depending on the size, shape and location of the lamp on the vehicle, and the atmospheric conditions occurring, the amount of time required to clear the lamp may vary from 2 to 6 hours.
Completely sealed headlamp assemblies (sealed beams) are still used on a limited number of models being manufactured today. These lamps require the replacement of the complete lamp assembly if a bulb filament burns out.

If moisture or droplets appear after being exposed to rain or washing, you can try putting some weather seals on the edges where you think the seal is poor. Check also the headlamp caps. In any case, if the moisture doesn't clear no matter what drying approaches, better replace the assembly.
The bulbs won't cause the moisture, but it is possible that an accumulated moisture on the bulb itself can disable it, although rare.

2006 Volkswagon Beetle, drivers side headlight, high beam not working


Instructions
    • Turn the headlight switch on and inspect the headlights. Make sure to check both low- and high-beam lights, and then note the position of the bulb in the headlight assembly. Low-beams are in the top cavity of the assembly and high-beams are in the lower cavity.
    • 2Turn off the headlight switch and then remove the keys from the ignition.
    • 3
    • Open the hood and locate the seam to the headlight assembly and the side fender. Locate the headlight assembly release lever and push in on it slightly to unlock it and then pull it all the way up until it stops.
    • 4Place a blanket or pillow on the ground in front of the headlight assembly. Push the assembly outward from behind with one hand while being ready to catch the assembly with the other. The New Beetles use an adhesive sealant to protect the back of the headlights from exposure to moisture, so you'll have to give the assembly a push from behind.
    • 5Pull the wire harness plugs off from both the high- and low-beam blades of the respective bulbs.
    • 6Place the assembly on the blanket or pillow. Release the wire clip to the faulty headlight and then remove the headlight bulb.
    • 7Open the package of the new H1 bulb replacement without touching the glass portion of the bulb with your bare skin. Oils in human skin will damage the bulb. Handle it only by the metal base of the bulb insert.
    • 8Insert the new bulb in the appropriate headlight-assembly cavity and reattach the bulb retaining clip to lock the bulb in place.
    • 9Lift the assembly up and plug the wire harness plugs back into the respective blades of the bulbs.
    • 10Push the headlight assembly into its cavity, but before locking it in place, check the lights by turning on the headlight switch.

1999 ford taurus with moisture in the headlights


Most headlights lens are sealed up to prevent this problem. A broken seal or a crack somewhere opened up to let in moisture.
You can drill a small hole on the lowest part of the plastic headlight housing to let the water drain out. Or, replace the plastic headlight assembly with a new sealed one.The plastic headlights turn yellow and cloud up over time (not because of moisture inside, because it's plastic getting ruined by the weather and the sun). This problem reduces headlights from putting more light on the road.
The only thing you can do with moisture inside the headlights is to drain out the water that builds up. The seals on the headlights are bad right now and are going to keep letting moisture in. I would replace the both headlight assemblies for new sealed, clear ones.
