VVolfSocks Posted June 24, 2022 Report Share Posted June 24, 2022 Hello all, Thank you in advance for your assistance with this! Little bit of contextual prefacing: I drive an S70. Recently replaced the radiator, starter, and had to rebuild the engine, all about two months ago. Has been running reliably and sounding normal since. The last week or so has been much more humid than usual as it's been storming mildly frequently. Because of this, I didn't think much of finding my windows entirely covered in fog upon entry yesterday (standard condensation). The issue arose when I tried to make a 5 minute drive. Normally full heat would remove the condensation, but only seemed to make it worse. this morning is when I really started noticing an issue. Very little weather occurrences overnight, no reason for condensation, but the same fog issue. Driving to work in stop and go traffic prompted a white smoke to come out the cabin air vents, and the continued recondensation of the windows. Vehicle gets incredibly humid after very little time, especially with the air fans on. still sounds normal and operates as it should. Only issue I'm finding is the cabin vents. was looking into it and all I found was a potential need to replace the heater core, buy I'm wondering if anyone else may have some ideas? I've never had this happen before and a bypass isn't an option because winter 😕 thanks again for your help! I hope you have a great rest of your day Link to comment Share on other sites More sharing options...
Zappo Posted June 24, 2022 Report Share Posted June 24, 2022 Not potential, you need to replace the core ASAP before it lets go completely. The longer you wait, the worse it will get. Luckily, it isn't that difficult to replace. I have done mine twice and there are videos out there on how to do it if you want to tackle it yourself. I'm sure Robert DIY has a video on it.

Will do at a junkyard run on Sunday and pick up a couple temporary, till I can get a new one delivered and installed. Will definitely have a look at some of Roberts videos on the topic!

mojojo Posted June 29, 2022 Report Share Posted June 29, 2022 Aside from the heater core recommendation, here's one that goes unmentioned also. If you have a sunroof, makes sure the drains are clear and free of debris. Moisture in the cabin can cause condensation to form on the windows inside of the cabin. Additionally, table note of the position the car is on when you park it, i.e. the front is down or the front is up. Link to comment Share on other sites More sharing options...
