How do you repair a CD changer that will not eject the CD's in an Infiniti FX35?

To repair a CD changer in an Infiniti FX35 that won't eject CDs, first, try resetting the system by disconnecting the vehicle's battery for a few minutes. If that doesn't work, check for any physical obstructions or debris in the CD slot. You can also attempt to manually eject the CDs using a paperclip in the manual release hole, if available. If these steps fail, it may be necessary to consult a professional or consider replacing the CD changer.
