Appears I may have found the parasitic draw on my 2005. Manual states for 2005 model ECU-B2 10A is for power door lock system/ power windows. If anyone may have suggestions on where I can chase this ghost first would be greatly appreciated. Amp reading with fuse in .20 and with fuse out .01. Drivers door actuator quit working over 3 years ago but parasitic draw just started.
Thanks!
 
Could it be another actuator failing? Is the draw the same 100% of the time, locked, unlocked? You also may consider if draw decreases after vehicle sits for a bit, I think it takes time for some of the systems to shut down. Also, door close switches have been known to fail which can cause strange things (confuses system order).

To make sure, the test is done accurately, make sure you trick the vehicle so it thinks it is closed and locked to make sure the vehicle shuts down otherwise it stays in a standby state for a while waiting to receive a instruction. By this I mean if the door is open, latch the door lock with a screwdriver, same goes for the bonnet. If there are any other switches keep them pressed. If you have a alarm then disable the sensors and lock the vehicle. Wait 5 mins and the test for power drain, if there is a drain wait another 10 mins and test again. First place to look would be the faulty door actuator.
 
Hey @joe dirt, did you ever figure this out? I have the exact same issue, same readings. I hope in 6 years you found some peace, any feedback on what worked?
