Turn van off. Open & close drivers door, wait for everything to power down. Turn van back on and push button to close CD/Nav opening. It will close. Having an issue with CD player also.

Just below the CD/DVD tray there is a tiny hole. Insert a straighten paper clip in this hole and gently push the paper clip until the CD/DVD tray pops out. You can now pull the tray out until it is in the fully opened position to remove the disc.
Try pushing the eject button to see if the tray closes, then push the eject button to see if the tray opens.
If this foes not work then the CD/DVD drive is faulty and it needs to be replaced.

There is a small belt under the loading tray which would have gone slack ( loose ) and the sound you hear is it slipping on the motor pulley. If you are confident you can remove the mechanism and turn it upside down and access this belt. Dismantle only if you can get the spare belt or your efforts will be in vain.

try to re start the power first to reset the supply in which the door unable to open and then push the open/close button to open the door. if still won't open maybe their is an stuck up at mechanical part, so turn off the player then use a Phillip screw driver to loosen the screws and to remove the cover of the DVD player .you can now access the disc mechanical assembly of your DVD player, remove the CD first and then check if the plastic gear is mis aligned or the the drive belt is broken.much better if you can apply silicon grease in plastic gear for smooth operation.then make sure the open/close button is ok, good luck and good day.

There should be a small hole on the front panel of the DVD-ROM. Take a paper clip and insert it into the hole and push to open the tray. If the DVD-ROM tray continues to malfunction, you'll need to replace it. DVD-ROMS run anywhere from $25.00 to $75.00.

the motor belt are weak or lose / need to replace to accuirate turning out the tray.
