Thanks Paul. I think I should clarify. The CD changer has not worked at all since the head unit started displaying Error Code 4 when I pressed the CD button. I haven't been able to eject or load a CD since then either. I HAVE had the display showing that I had 5 of 6 potential CDs in the changer, and the radio continues to work fine. Now, after disconnecting the battery, there is no display for any CDs present, even though they have not been ejected. The Load and Eject buttons still don't do anything, and the CD button will not switch the stereo from radio to the CD changer. I feel like my next step is to replace, or upgrade from the changer/cassette desk stock option to a more modern CD player / bluetooth iPod connection. Thanks again for any thoughts or insight. James

Hey guys, This is only my second post on this forum although I have received numerous tips on here over the years. I have a 2004 IS300. When using either the key fob or key in the door, all door except my passenger side front door will lock. When using either the key or key fob, all doors will consistently unlock. This is an improvement, as for about a year, the door in question would neither lock or unlock. Is this a repair that can be done, or is it a must that I replace the actuator? Thanks guys!

Hi guys, First time posting here as a new member, but I have received a lot of helpful advice from this site in the past. I've got a 2004 IS300. The 6-disc CD changer had been giving me "Error Code 4" for months, and I finally disconnected my battery to see if that resolved the issue. After reconnecting my battery, the head unit no longer displayed 5 of 6 discs in my changer, or any error code. In fact, while the buttons (CD, eject, load, etc.) haven't been able to switch over to CD for months now, now my head unit is no longer even recognizing that I have CDs in the changer. It's acting as if the changer isn't even there, even though the radio and everything else work fine. Manually attempting to insert a CD doesn't work, as the loading function isn't working. Does anyone have any advice on how I might be able to restore, or do I have to replace? Thanks!
