The vent temperature is 75 degrees. The compressor does kick on. The temp. sensor lights up and goes off when you turn the ignition.....meaning the red led on the lowrange/aux switch panel.......the fuse is fine now after I replaced and it did not blow the fuse again.........I have also tried to take it to hot and dropped it down to cool into the blue range and it cools to 75 degrees when its not hot outside.....otherwise the temp inside is 90 degrees
