Just had my 2003 S60AWD battery replaced. He attached a battery to the plug under the dash to keep the computer codes. Afterwards, the turn signal stalk won't do anything (turns, high beam etc.) and the wheel radio controls don't work. Tried cental locking and unlocking as suggested in the manual, with no improvement. Anyone have any ideas??

 

Disconnect the battery for 30 minutes to reset all the computers and see if that helps.
