The battery is being drained and i believe i've tracked it down to the ac control assembly above the the radio. When i unplug the fuse for the "ECM body" it no longer drains power. I know the "ECM body" operates some parts of the "AC Control Assembly". Might it being something else before it buy a new one? I also tried unplugging all of the ac solenoid relays but no luck.
You diagnosis is wrong in my opinion, that module will not drain a good battery, first have the battery load tested (Autozone and others do the test for free), if it is good then look for some kind of light left on or staying on, suspects are visor vanity lights and glove box and console lights.

You can save a LOT of money by fixing it yourself.
All that is wrong with the knob are broken wires from the knob's PC board to the main PC board on the AC control.
All you have to do is remove the AC main control, take it apart, and resolder the broken wires from the PC board with the knob on it, to the main AC pc board. There are 3 wires, any number could be broken.
If you take it apart and solder the broken wires, this WILL fix your issue. Just make sure you put the wires back exactly where they go.
A FIXYA rating (4 blue diamonds) would be most appreciated for my assistance.

Check the freon charge.There is a low pressure cut-off switch to kill power to the compressor & prevent damage to the compressor due to lack of oil.
SOURCE: Heater/AC control no longer allows change in temperature
You have one of two possible problems.
1) The temperature shaft retention nut is loose behind the knob
2.) The wires to the potentiometer part of the temperature may be broken.
Either one is common to this vehicle. The replacement of the AC controller is about 900 dollars. If the wires are broken, they can easily be reattached to the circuit board via soldering. What you would have to do is remove the control box from the dash, and disassemble it. Once the unit is apart, there are 3 wires from the temp knob to the circuit board that need to be re-soldered. The unit CAN be repaired, as opposed to the expense of replacing it.

Don't mess with struts unless you have a strut compression tool. You could get seriously injured. The nut is on top of the tower where the strut attaches.
