Hey guys, great to join the site. Wanted to know if anyone else with an ES has experienced intense cabin heat while driving hard at highway speed? I don't notice any change to the engine temp gauge, just scalding hot air coming through the (closed) vents into the cabin. It's bad enough that I always have to open the sunroof to help release the heat. I don't drive like a maniac either. It occurs at all external temps. Normal or something wrong?

It's a bone stock '19 ES sedan. Thanks!

So I fiddled with the A/C on all fan settings and then turned the car off and on. The vents stopped blowing hot during driving. Unbelievable. Thank you!

If the vent setting is set to fresh air, it will bring heat into the cabin depending on the temperature setting you have set. Putting it on cold and pushing the recirculate button should stop it.
