Radiance

i own a black 2001 Lexus ls430 and the stereo wont turn on. the radio controls dont work either. the steering wheel only gets closer to you and wont move up and down.
(i'm not familiar with the jargon.) The controls on the steering wheel work except the radio controls. the cruise control works also.
I also have a problem with my rear windows; they roll down by themselves.we have to hold the button upward so it can stay and lock the windows via the button on the drivers side door. everything else works great. the ac works fine. all the buttons work (except the radio controls its dead) 80 thousand miles on the car and it runs new. we are a family of toyota driver and this Lexus is amazing.

by the way its used, so i dont have much of a history to mention. i bought it with the problems i'm facing.


thank you (all) for any help you can give me.
