Is the air circulation system in a 95 Cherokee "always fresh air" or "always recirculated"?
I ask because a: there isn't a control for this like in other vehicles I've owned, and b: the AC blows OK (cool to cold) when the outside temp is below 80 degrees or so, but if it's hotter than 90 - 95 degrees out, I get cool to warm air from the AC. One friend says that AC's can only do so much, and it's probably trying to bring down the temp of the 95+ degrees outside air.
My compressor seems to cycle appropriately... I bought a recharge kit, followed the directions, but got no improvement after emptying the
18oz can. The gauge that came with the kit would show in the middle of the low range when the compressor was off, but jump to the middle of the OK range when it came on.
Now an AC shop says I've probably over charged the HIGH pressure side and should expect it to fail soon... They want $65 to test it (foldable into the inevitable repair cost).
Am I expecting too much from the AC or should it be able to blow ice cold in 95 - 100 degree weather?
TIA
