SOURCE: Two discs are jammed in

May be the discs stuck inside can get damaged.If you can see the disks then you can slightly pull the disks by player.If the disk tray cover is got close and disc is not seen then,with thin putty knife you can try to manually open the disc tray cover and open it and remove the disks.But if nothing is possible and every thing seems to be jammed then you will need to open the dash and remove the radio/dvd player out and disassemble the dvd player and remove the disk.Once the dvd player is out,its not very hard to disassemble the player.Its just fitted with screws.But removing the player out of dash and disassembling the dash is not very easy.--------- Dont forget to disconnect the battery before you proceed. --------- Click this link directly to get the procedure of instrument panel dash disassembly and removing the radio/dvd player out:--- http://technoanswers.blogspot.com/2011/03/how-to-disassemble-instrument-panel.html ------------------ This should help.Thanks.Helpmech.

Door has worn hinge. A body shop will have to fix it.

SOURCE: I have a 2010 yukon denali and the front dvd player works but the rear over head doesn't......is there any way to check it myself????.....

Check the fuses... the rear one may have a fuse behind the unit itself.
