The temperature gauge appears to be reading accurately and i havent noticed any change.
However why would 85 be at 12 volts unless the sensor was telling it to turn on?
My air hasnt worked in ages

The ECTS has a 99.999% failure rate and is cheap. Replace it and go from there. Your fan normally won't kick on until the temp gauge goes a little past the half mark.
There are two points at the relay that should be hot at all times. They are the power supply and the relay coil power supply. Both get their power from the same source (30A cooling fan fuse). The pcm provides a ground for the coil to close the circuit and turn on the fan when needed.
