What specifically are you using to measure the current? That seems high with no light visibly on and no motors running. If this is a stock setup what are the high current consuming devices, assuming that something hasn't failed?

1) ignition works fine.....?
2) A/C clutch none
3) heater blower motor- have not check yet....its not running
4) headlights pulled switch cable-no change
5) rear window defogger none
6) power windows none
7) horn works fine
8) windshield wiper have not checked motor is a Jules rebuild...but does not work...will pull switch cable to test next

There just aren't that many devices that can draw that kind of current constantly and not have some kind of problem show up.
