why would power suddenly go out in 2004 Thunderbird?
I opened the door with FOB and systems seemed ok, bell dinged when put key into ignition ready to start. Decided to rinse car off, turned key off, rinsed car, got back in, turned key, dead as a doornail. Acted as if battery was disconnected. FOB no lornger working, no lights nor hint of electrical power. I opened the trunk to access battery, checked terminals, clean, but noticed a slightly audible intermittent noise apparently coming from Power Distribution Box. I disconnected + battery cable & let it set for awhile. Reconnected, no noise this time & still no hint of power.
