Wrong! The number one cause of a failed acc II system, is a frozen aux water pump. The pump freezes and then it blows the amplifier behind the glove box liner.
The number two reason for the acc II not working correctly is the temp sensor tube that runs from the passenger side speaker grille to the blower assembly, with out this tube...the system cannot sample the cabin air.
