12 Disc Changer For Sc 400 No Longer Working?

[qwertyzap]

Hey everyone,

I just bought my 93 SC 400 87k miles last week from a dealer. I've been enjoying the car, especially the convenience of having a 12 disc CD changer. I was listening to my CDs and parked my car and went to go get a burger, and when I returned and tried to play my CDs it read ERR. Within the span of maybe 10 minutes, the disc changer stopped working. I looked up the ERR message in the owner's manual and it says that its what happens when you have a CD upside down; yet, I didn't even touch the car inbetween the time everything was working and when it stopped. I have 6 CDs in there, 3 regular and 3 CD-Rs. I tried switching them to different slots and even turned one upside down just in case, yet nothing works. Can anyone please advise??

TIA!!
