I had this horrible fogging problem inside my car, double-checked that the thing was sealing and found that the weatherstrip was bad and fixed it, but the problem was still there. It just didn't fog in the morning, only when it's running. I did some troubleshooting, driving with the windows down and turning it on and off, even closed off one vent and let the other go. Anyway, point being, above the vents is getting fogged to the point of being dripping wet. I read the forum for tips and found that usually there is also leaking on the passenger side floor, which mine doesn't do. As it is, I have the heater turned completely off and a mini car heater installed facing the driver's side so I can see while I drive. Basically, I'd like advice on how to fix it, if it's worth it and if it's more time-consuming than just putting the new engine in my RX-7 for a daily driver to park and cherry this one out.
