OK, so I have an 02 AP1 with a forbidden USA hardtop that has a lexan rear window. Every morning I come out and it is completely fogged up. Has anyone else had this issue or know how to fix it?

 

Usually a symptom of a water leak somewhere in the cabin, any musty smell in the car ?

 

Nope, none. I think the moisture is getting in because I don't have AC anymore so on the hot and humid days I always have the windows down.

 

Try anti-fog goggle spray on the inside. Also make sure the recirculate button is not on. Try to crack the windows to let the cabin draft.

 

not likely. I've driven mine through all kinds of weather conditions and never had that. I can see it happening occasionally depending on temps and weather conditions, but it if it is happening regularly check more closely for leaks. Trunk leaks with water ending up under the lower floor trim are common, as are leaks under the passenger side footwell.
