    Replace the 12VDC activated relay. When you turn the car off, the accesories circuit will disengage the coil leaving the circuit "Normally Open".

    I have a 2001 GS300.... I can email you the schematic of the relays I am talking about... but I also have the Mark Levinson Sound System... so it MAY be different... (highly doubtful, however in the field of manufacturing)...
    Sucks that you cannot attach pictures to this post on this website...

    PARASITIC LOAD TEST WILL FIND AND CONFIRM WHICH CIRCUIT IS AT FAULT.... See a qualified MECHANIC!!!... When you get your car back on the road...

    Replace the Radio/ACC relays first... if that does not solve the issue (stuck relay) then you have an electrical issue that needs to be diagnosed further... I agree with Pushrod AFTER you replace the relays first...

    In regards to the new dash that you just installed... was the dash verified to have worked? Once again, if not, I would have a certified (electrical) run continuity tests on each lead... or if they have a test bench, hook it up to that to verify functionality...

    yea the old dash was wrking but it had a lot of cut wires i didn't even have a switched 12v wire for my radio so i took my old dash out and went with a new dash with uncut harness i put all the plugs where they are supposed to go now the cluster turns on but not my climate control or my clock could it be because i don't have my center console or radio connected yet
