have you tried to clear the error code in the sterio yet

if not do the following , it could work or not
1 turn on sterio on am or fm
2 press and hold preset #3 and #6 at the same time
( the radio will go into a speaker test mode playing sound at each speaker one at a time)
3 press the #2 preset and it should say dtc codes (that like reading error codes for a check engine light but this is only for the radio)
4 press the eject button for the cd player (this clear the dtc codes)
5 turn off radio (this saves what you did)
like i said it could work or not. after step 2 if you push other buttons(1through6) it will go into other test modes. best of luck hope it works on yours!
