Unit work great then water from cloded drain backed up and various items were effected. Replaced BCM and resolved many issues but I can't get the changer to work. Radio is fine but not the cd changer. C5/1998 Coupe. What might be the problem??????
Check for a reset button on the changer. It will be a small black button you will need a ball point pen to push...or something simular. It might be behind the cartridge door. Start with that. If there is not one try a hard reset by discontecting the cable for a few minutes. Also there might be a fuse for the changer.
Sorry I know it is not very accurate but doing all those things will only take a few minutes.
