I removed my entire AC system to shave the weight and avoid fixing it on my 92 Jeep Cherokee 4.0. In the summer it's an oven inside. I was able to swap in some wing windows but even with the 4 windows down and wings open the rear cargo holds a a massive amount of heat. My idea is to remove the rear 3 windows to let the air flow freely. Someome cautioned me about exhaust fumes. Should I leave the rear door window installed or can they all 3 come out. Has anyone done this aleady?

 

tint the windows with uv tint the darker the better it could cool down the back of the truck by 20 degrees maybe more.. exhaust fumes will come inside if you remove them..... do your front doors have wing windows? they help with air flow.. if you can find some of those...
