Toyota tacoma 2003 ac control assembly kills battery 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.

Need a faster answer?
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.
