Possibly the same as mk1-2's? No idea, anyway....

Is there a modification you can do to get hot air out of the vents aiming at the driver/passenger?

It will make me really happy if there is!

I think there is you know. Pretty sure it involves putting some plastic on the outlet that blows at the floor to direct it into the side vents. But I can't be sure. I think Eric did it in his coupe

yeah theres a how to out there somewhere
