Battery drain resolved to Fuse 1 in distribution box which just supplies the cabin fuse box. When Fuse 1 is pulled, the 230mA drain drops to 30mA which is normal. Keeping in ammeter in plase of the MaxiFuse 1 I systematically pulled every fuse in the cabin fuse box under the steering column. All but 2 have no effect. The 2 are "Battery Saver" and "Wiper & VAPS". I don't believe they mean windshield wiper motor because that has its own 30A fuse. These fuses are either both 5A or 5A and 10A, maybe they mean the wiper fluid pump? Anyway, clearly there are some relays involved here too, in the circuits that these 2 fuses deal with and it appears that one circuit is fed from the other, normally. Clearly one of them feeds the interior overhead lights, as when I pull either they go out. I am wondering if maybe a relay is stuck energized or something. The factory alarm is a pain in the butt but I finally found out how to put it in valet mode - I would like to completely diasable/remove it if you can help because that can be a culprit. I know many alarms attach to this interior light circuit to pick up that draw to trigger their alarm so they dont have to put in all new door switches. Does anyone have any wiring diagrams pertaining to these 2 fuses and their respective relays? Or how to disable/remove the alarm permanently while still keeping the remote door lock/unlock function?
P.S. I am very competent with electronics/engineering and equipment is not an issue. I am not as competent with cars which is why I am here ;)
have the same problem?
