    My car doesn’t have insulation either but the AC absolutely makes a difference. Maybe your AC unit isn’t working - 40 years is a long time for a unit, may need cleaning or recharging, or just replacing.

    Come to think of it, the house I grew up in didn’t have insulation either, and we’d have died with window AC units in the summer.
