I've located the source as being from the sunroof. There is condensation forming. Does anyone have any suggestions to fix this?

 

condensation is forming on what, the glass? thats normal. its called condensation.

 

Condensation is forming throughout the vehicle. To the point where it's dripping. I have to wipe everything down in order to see through it. It's like if I were to spray water into the car with a hose. So, basically, it's a lot of water forming on all the interior glass and then dripping onto the seats and dash.

I think the source is coming from the sunroof. Any ideas on how to fix this issue?

 

well there is a seal that goes around the top of the sunroof you could replace, but there is also a vent in the rear drivers side quarter for ventilation, i would check that first. Condensation to the point of wet floors is a common problem in 90-95 civics because of poor ventilation. Other then that i would say make sure you keep your a/c on while the heat is on, the a/c is a natural dehumidifier, thats why the defroster works best with the a/c on.
