I have an old Diamante from 2003. Recently enormous quantities of moisture have been collecting inside. It drips from all the windows, not just fog but thick droplets. If I wipe them with a towel, they just bead and drip even more. I have to go over them several times to actually get them dry. God knows what this is doing to the electronics.

The dampness all seems to accumulate on the front passenger floor. The carpets are absolutely sopping but the rest of the car is dry, except for the windows. I don't know if there is a lean to the front left. There doesn't seem to be.

This started (at least I first noticed it) a couple weeks ago. It is still going on though the car has not been running. It is really extreme. I have never seen anything like it before. I don't know what can be causing this. We have had several cloudbursts of very heavy rain over the past couple weeks so maybe water has accumulated somewhere from that, though I can't find anything. We have also had a spell of sunny weather, bright in the daytime and cold (but not freezing) at night. Maybe that is causing excessive condensation. The car lives outdoors. The windows are dripping on the inside, but completely dry outside. Or maybe it is the air-conditioner leaking. I can't figure it out. Nothing has been running for the past two weeks.  

Today I went over everything with towels and a hair dryer and it is all pretty dry at the moment. It will be interesting to see what happens tomorrow. I would be glad to know what others think of this. I have never experienced anything like it before. Condensation is one thing, but this is sopping wet. The car has been closed so no ventilation. The water is all coming from the inside.
