battery drain

try cleaning the console switches. sounds like they may not be totally releasing and continuing to draw.

 

I have never seen the 360 circuitry but know IF windows were fed battery voltage with switching done by providing a ground, definitely it could drain the battery as you describe. I would think the problem is either in a window motor or a partial short in wiring leading to the motor, perhaps at the door hinge area.

You mention removing 2 fuses. Try isolating the drain to one side of the other by only removing 1 fuse. Then if you can, remove the door panel on the offending side, and unplug the window motor. This will narrow it down to the motor itself or the wiring.

 

Check to see if either door handle is not returning to the rest position. Both the outside and inside door handles have microswitches on them that activate the window drop down feature. If the handle does not return to rest, it can keep the microswitch active, which will not allow the window ECU to go to sleep. Depending on the type of inside door handle you have, there might also be a microswitch for the door lock switch. If you have to pull up on the lock switch to lock the doors, check to make sure that the microswitch is working properly. Usually you will be able to hear the switch click as it opens and closes. Hope this helps, I have seen a lot of the inside door handles no longer returning to rest as the cars age, especially on the 550 and 456, but have seen it becoming more frequent on the 360.

 

Something else drawing power on the same circuit? Such as a badly installed alarm system or tracker device?

 

Current drain in a 360 should be about 20-25 miliamps. To get a good measurement you need to have the door closed and all systems off and wait about 5 minutes with amp meter connected for all the electronics to shut down.

 

I'm with Rifledriver and Ferrarichallenged, micro switches will keep the window E.C.U. awake. Usually a 180ma. draw. The way I determine which door micro switches are at fault is to unplug left door jamb connector, if draw is still present disconnect right side door jamb connector. The most common draw comes from the outside door handle switch which 9 times out of 10 was installed backwards. hope this helps you further on your diagnosis.

 

You must wait at least 15-20 minutes each time you open and close a door, disconnect a component or fuse, etc, for the car to "go to sleep". If the car is "awake" you will find draws in all kinds in systems, that are only shut down after the stated period of time.
