I have a 99 cadi sts. I dont know what happend. Went to replace air ride compressor. after installing it. went to crank car waiting about 45-50 sec. But nothing no dash lights nothing no clicking when trying to start. no radio i put the key in nothing dash board secirity light flashing only so I took battery to Auto Zone for charge and was told battery excellent. but nothing comes on when new battery replaced. Oh yeah before I got battery charged it would click a little when you try to crank it so I thought starter but no dash light no power door locks no radio nothing comes on. Please can someone help me.

 

Does this sound like a pass key issue. Or BC module. when I turn on the alarm no horn soun but light flashes. Weird!!!! No power!!! Please help
