Hi, the moisture in the headlight units is most likely caused due to a failure in one of the rubber seals where the bulbs push through into the headlight unit.

Have a check to see if the bulbs are seated properly, they are normally held in place by metal clips, sorry I'm not familiar with this particular model so can't give specific advice. If the seals are ok, could be that the moisture managed to get in somehow, and now is sealed in the unit.

To get the moisture out, you'll need to remove the bulbs from the headlight unit so that the moisture can evaporate out and then re-fit the bulbs to seal the unit again.

Hope this helps.

The headlamps on the the Venture, Montana, Silouette come with NITROGEN in the lense to displace moisture and keep them cooler. When you change the bulbs, you should take out the lense and hold it lense side down to prevent the nitrogen from leaking out. If you lose the nitrogen you could replace it by going to a tire shop and getting them to fill an air tank and doing it yourself. This should take care of the condensation.

How do I remove condensation from the headlights of a 1996 GMC Suburban 1500?

The reflectors and the housing usually have a small port or tube device to allow air to enter the housing to stop condensation. If there is a tiny tube or port that could be clogged, or the gasket to the lens is worn and leaking or cracked. You will have to dry out the condensation first before you reseal the headlight lens and housing. This means you will have to take it apart.

Headlight condensation

Try by using a hair drier. Remove head light assembly from vehicle. Remove the bulb for the head light, Use the hair drier through the bulb hole to remove condensation. If water gets in the head light. Drill a small hole on bottom to release the water. Some times you can remove the condensation from the head light if its not bad by using the drier on the outside of the head light, with out removing it. Good-Day!

The headlight socket is probably not making contact with the light bulb, you may have to replace the light socket. If you get a lot of condensation in there, you make want to purchase some dielectric grease and put a bit on the bulb when replacing. This will keep condenstion away and prevent corrosion on the contacts.

Saturn sc1 3 bulbs burnt out at one time after I just replaced both headlight bulb

Hi Legalass, Condensation will be caused by water or moisture entering the head light unit. If the lens is cracked or broken or the cover are not correctly fitted that will answer that part of the question. I think for the second part of the question you should take the vehicle and have the voltage regulator output checked. It is possible that the alternator is being allowed to over charge and when it does, it may be blowing the bulbs! Regards John

Condensation inhead light

You may have a small rock chip (hole) in the lens that could be plugged with 5 min epoxy , or the bulb may not be seated and sealed properly. If the seal around the outside edge of the lens where it meets the plastic housing is leaking , I would get a new headlight from an auto wrecker and change it.

I am in the process of buying a jeep Laredo which seems to have condensation inside the headlamp glassis it possible to clean this/replace the glass/or is it best to buy a new pair

Condensation is deemed to happen if ambient temperature is lower than inside the headlamp and humidity inside of headlight is too high.
From a headlight design perspective, you cannot lower ambient temperature. Not much can be done with temp inside headlight either. However, humidity levels on the inside can be reduced. Most designs usually have 2 or 3 air vents to keep humidity below condensation threshold levels.
This might sound complicated, but the phenonomen is exactly the same as windows in a winter home and humdity levels inside. Too much showering, and bathroom window fogs up. Venting will reduce condensation.

You might wonder why headlamps are not designed to be 100% air tight, so that no humidity enters? Well, that would be in an ideal world with no heat losses in bulbs. As the headlights goes through continous warm-cold-warm-cold cycles as you turn light on and off, the air and plastic will expand and retract. This creates pressure changes, which will move a slight amount of air in and out. So instead of forcing the air to be inside, air is moved through controllable passages, so that minimum of road dirt will enter.

If condensation disappears within a week. Moisture can have been sucked up in high pressure wash. This should normally dissapate within a week by itself.

If condensation amount stays constant, then there is crack(s) in headlight that lets in water. This can be siliconed, depending where the crack is, or a replacement headlight should be considered.

Condensation in my headlight

Okay if you have condensation in them now take out your headlight housing and your bulbs. Let them sit in the sunlight until the condensation has evaporated and use a glass cleaner to clean up any spots. Then get some clear RTV from an auto parts store or Wal-Mart maybe 2 or 3 tubes and seal all the around the headlight housing. If you have projection style headlight the rubber boot on the back can let in moisture if not properly sealed. Make sure this has a tight fit and if you notice a hole use some of the RTV around it. Repeat this procedure with the other side. I hope you have good luck with your project!
