Myisalwayshasproblems

Ok, so I have a 2002 IS300, Automatic. It is causing me hell. I will try and be as short and sweet with this as possible, as I need all the help I can get. Helpful comments will be greatly appreciated and I will try to answer any questions as soon after as I can. Problem: when the key is removed from the ignition, the car still has power to the following parts: Cluster Daytime running lights/ headlights/ fog. Climate control, a/c, clock, and temp. relays that click alot under the hood seat movement. sunroof (the only way to kill power is to unhook the battery) I have access to tons of parts because I work at a shop that dismantles these cars on a regular basis. so here is a list of parts I have changed... Replaced: driver fuse box, and pink box. anti theft warning module (seemed to help for a day) daytime running light module (seemed to help for 2 days) abs anti skid module ignition switch. also tested the immobilizer. car has had a front end collision in the past, very minor, fender headlight hood, and possibly was stolen at some point, before my ownership. I am also tracking down a problem with the abs/trac system, code C1226. Seems unrelated though.
