I am just looking at a s500 coupe,for sale locally,kinda cheap,with some weird problems.Car was without a battery(they told me) for a couple of days,since they installed the new one,no speedometer/odometer(electronic),just shows the old reading,no radio,not even the security light,no steering adjust(up/down/back/forward),windows will not close properly,all the way...I was trying to see if it might be a fairly easy fix,so,I can get the car inexpensive and synchronize windows and replace fuses/relays...any detailed help will be appreciated.
