2004 TL w/ nav, battery went dead in July and as the battery in the car was 10 years old, replaced battery.
The car is driven maybe once a week, next time used, battery dead.
Checked the HFL while charging the battery, and sure enough it was warm when car off.
Great, removed HFL.
Wife went to use the car a while later battery dead.
Time to do some checking.
470Ma draw when engine off and car asleep.
Narrowed the problem down to the infamous #7 7.5 Amp back up fuse circuit.
When #7 fuse pulled, 14/16Ma.
That's great, but which circuit is the problem as it controls:
Audio, HVAC display module, Clock w/o nav, Combination switch control unit, Gauge control module, Front passenger's power window switch/control unit,Immobilizer control unit-receiver, Navigation unit, Security indicator, Power window master switch, Power mirror control unit, XM receiver unit.

The answer is the Power Window Master Switch.

Maybe this might someone in the future.

i wish everyone was as thorough in troubleshooting as you are Turbonut

Great job! BTW, it's mA.

Dumb mechanics. I'll need to remember that next time.

Unless he was measuring 470 mega amps. Ouch, talk about a hot wire!
