All of a sudden my 1994 lexus sc400 instrument panel wont go off, even if i take out the key entirely, i can still press on the break and shift it to R or D or whatever. it should be entirely off, the blinkers still work and makes a weird noise when i do turn on the blinker when the key is out...its been really cold here in NY dropping to around 5 at night maybe below...i called my friend and he said that it might be a contact switch or the ignition module is stuck or some kind of relay. the symptom is that when the key is entirely out, it still seems like the stage where the car is about to start, one notch below the ignition notch, all the lights are on. so for now i have to disconnect the battery whenever i park or ill run out of juice.
