Saturn Ion 2003 CD player Err code

2003 Saturn Ion CD player Err code. Was asked to elaborate & give more info to my problem. A few CDs I have had trouble getting read in my car stereo but worked fine in any other CD player. I cleaned the CD w/ a good cleaner that's worked. Found out that my car stereo doesn't work well in cold weather. As I drive to work early, CD would continuously eject & LOAD would appear on readout. I would continue this process until the disc was read which would take anywhere from 5-25 tries or not @ all until after work when the weather was warmer. Got into my car one morning @ pressed AUX button to play CD. Disc was ejected, but LOAD did not appear. Now when I press LD/EJ button, LOAD does not appear on readout. The slot #3 that ejectedy disc should appear empty but shows a disc is in there. Now I can't eject or load in any other slot. Err appears every time I try to load or eject, period. Interesting note: about once every month while listening to a CD, the music would stop, all slots would flash on, & the disc I was playing would continue after 5-10 seconds. This almost seemed like the player was resetting itself. Radio still works. Went thru 50+ pages & read I could unplug my negative battery terminal & this might reset my CD player, but that was for a Honda. This is a stock Saturn Ion radio. E-mail [email protected]. Thanks.
