Hi all ive done a search on the forums but im still having problems. I changed all the bulbs in the headlights a few days ago. The day after changing the bulbs i noticed the drivers side headlight was badly misted up, never happened before so i popped the bonnet and found the large rubber cap had come off the dip beam so thought thats my problem. I used a hairdryer to dry it out put everything back together and washed my car, the headlight misted up again so i removed the airbox again and used the hairdryer again. Seemed ok this morning even after a nights rain but after finishing work it misted up again. The rubber cap is still on and i put some silica gel in the headlight. Anybody have any other ideas? Cheers.
