Ok....outside temp is 108°F, car idle, engine temp at 85°C, a/c on w/ low speed fan I'm getting 61°F at the center vent. Same setting with hi speed fan I'm getting about 58°F. Driving at 30 mph, a/c with low speed fan I'm getting 43°F. Same setting with hi speed fan I'm getting about the same. My conclusion: there must be something amiss or it's just the way the insulation is. Ps2cho, our climate is exactly the same. I let my car sit out in the sun for 45 mins before doing the tests. When I got in my car I clocked the inside cabin at 129°F. I'm now wondering if making some sort of insulation around the blower motor plastic capsule would help. While these cars are great, at the time of production they used and came up with things that were available to them at the time of production. Fast forward 25 years and there are new ideas and material that go into production. I would say even a 2001 base model Kia would be better at cooling under the same exact scenario.
