Cracking the windows in the summer, which lasts six months in Arizona.

[cbaber]

I've always kept my windows cracked while my car is in the open sun and I plan to drive it again that day. I haven't measured temperatures, but it does seem to keep it a bit cooler. The inside of a closed car can me much hotter than the ambient temp. thanks to the sun.

I can't tell you how many times I wish I had left the windows cracked. My drivers side A-pillar has plenty of battle scars from me breaking into my own car with a wire hanger because I locked the keys inside. It's so easy to break into my car I don't even lock it anymore.

from 11-2:30pm in 80F+ heat the UG reads itself in the 160F+ operating temps imagine what the inside car temp would be

Do you put the shade inside the car ?
It'll work far better when on the outside.

Would it get stolen if you put it on the outside ?
I can't recall anyone saying theirs were stolen
(here we use them in winter to keep the frost / snow off the windows)

I now have a car with fold-out rear windows again - old Jap style , even though it's a 4 door (VW being cheap) - and I like having them open for ventilation unless it's so hot the A/C has to be on.

Yes, it would work better on the outside and create less of a mess, I just do not know how to keep it there!

I only recently got my ac fixed, last year was over 100 for over a week, I wasn't doing that again.

What I noticed about the heat from leaving the windows up is that not only did it get hotter, but the interior itself gets heat soaked and continues to radiate heat until it is cooled down.

Is it a bit oversized where you could stick just the edges inside, and then roll the windows up to lock it in place?

Heh. No, but I guess that I can use a cargo strap!

In a car with sunroof, it can be left popped-up to leave hot air to get untrapped.

It is a bit oversized so it can fold round the A pillar and be locked by the doors, rather than the windows.
I will add a photo soon. I'm on my tablet now.

So here it is:

As you can see it has 2 flaps, but is just wide enough to get clasped between the door and the A pillar anyway. Makes it more wind resilient.

Front is alu foil, back is thin plastic foam. It is a bit worn from frequent use.


Rolls easily, weighs just a couple of ounces.

They sell these for a couple of euros in general auto parts stores.

Had it on today, full sun, ambient 25C, windows closed. Temp inside on return was 36 Celsius. Beats cracking the windows imho.

Well, ours certainly do not have those flaps, at least I have not seen any, but that certainly would do the job.

Mine will do the job, but it looks a bit funny, which does not stop an Ecomodder, right?





Curious thing is, the doors do not have frames, the windows roll into the body, so it is a bit of an either-or thing, eh?
