I am currently leasing a 08 Acura TL and every time after it rains it feels like a humid sauna and it fogs up from the inside. I am hoping to buy it but the dealer has failed to find a broken seal or what is causing this issue.
Please help asap!

 

could be a number of things. does it happen during all rain or just when its very heavy? leaking windshield, body seam, torn door moisture barrier inside door panels, stopped up door drains, leaking trunk etc etc etc.

 

Like mikedog4 said, look for leaks or plugs. its the only cause for this, since your in a lease shouldnt the dealer fix this?
Also look at the sun roof drains, its the number one cause for leaks. the drian goes into the quarter panel and if it becomes un hooked it will do this and cause rust in the long run. Good luck.

 

Don't run around with recirculate on. Turn it to outside air.
