My 03 Z seems to have foggy headlights now...I have cleaned them but it seems like the foggyness in the unit. Has anyone dealt with this?

 

Mine has that sometimes. It will go away in a few days. Leave it in the sun for awhile.

 

Did it when I first had it...

It quickly subsided. Like Shane said, let it sit in the sun.

 

I had mine replaced for free under warranty at the dealer.

 

can have it replaced, but headlights are not sealed on the backside. so humidity can get in. and in certain conditions it can fog. ussually this will go away on its own eventually. if its REALLY bad and all the time, then the seal on the front of the housing might be leaking(this would let alot of water in on a rainy drive); then get em replaced.

give it 1-2weeks, if it gets worse go to dealer. itll probably go away.

 

There is a TSB (03074) for what you foggy headlights. <ttp://www.nissanhelp.com/Bulletins/350Z/2003/2.htm>
