Anyone having this problem in their IS??

After using the AC. I have it on fresh air, and ive never seen this amount of condensation on the vents. Not even on my 2is350. It's happening ln all 4 front vents. It's draining condensation at the drain pipe under the car so I'm not sure if it's normal or not on this Generation

 

Is it extremely humid outside? What about inside your car?

I don't consider this normal, as I live in TN where it gets very humid during the summer months and my IS doesn't have this problem. But also, when I have my AC on I normally have it on recycled air, not fresh. I would first think to check your condensation drain pipe under the car, but since you mentioned it's doing what it's supposed to, I'm not sure where this extra "condensation" is coming from out of your vents.

 

When I have the AC running it's on recirculation, but when I turn it off I put it to fresh air .never experienced this before .had the car for 3 weeks now so I'm thinking something is up... I guess I'll have the dealership take a look at the ac components. Does anyone know if it's maybe a poor ckndsnsor unit? Or evap coil?

 

Also there's no condensation when it's on recirculation .only when I switch to fresh air. About 1-2 mins later a ton of condensation

 

Sounds like it or something's backing up. Just like you, I've never seen that much moisture/condensation with the AC on ever... through the vents.

 

it not an ac issue ,I bet because u have it on recirc thats as cold as the ac air can get ,when u introduce outdoor humid air its condensing on the cold ac vents ,that r pro ice cold . has nothing to do with condenser or evap coil

 

But doesn't everyone have it on recirculation when the AC is running .. when it's not running I turn off recirculation and put fresh air .

heres my guess opinion.

when u have it on recirculate there is n o humidity in the car which is why u don thave any.

BUT as soon as u put it to fresh air now ur letting in all the humidity into the car which is going thru ur vents into the car and since the vents are cold the moisture forms on the vents


think of it as a cup of glass with ice water in it. when ur inside the house with the AC on u might not see any or a little moisture forming on the glass...…… but go into ur backyard then watch moisture form on it like crazy and drip
