I hear you. My car's windows don't go down and the aircon doesn't work. So, after it sits in the parking lot at work for 8 hours, I'm riding in a furnace. Temp shows it was 103 outside, but inside it had to be at least 120. Luckily, I only have a 15 min ride home. I got out of the car, and it actually felt cool outside! I walked into my house (central air) and got immediate chills. I think the sweat was freezing on my skin!
To make it worse, we've had thunder all around us. I just want it to RAIN to break the heat!!
I'm living for fall right now.
