* Swing-out doors: These are like standard car doors, hinged at the front and opening outwards. To open them, simply pull the exterior door handle. If they're locked, you'll need to unlock them using the key or remote.
* Sliding doors: These doors slide open along the side of the van. There's usually an exterior handle to pull, and possibly an interior handle as well. Again, they'll need to be unlocked before opening.
If you're having trouble, check these:
* Check the locks: Make sure the rear doors are unlocked. Try using the key or remote to unlock them.
* Check the handles: Examine both the interior and exterior handles to ensure they're not broken or damaged. Sometimes, dirt or debris can interfere with their operation.
* Check for obstructions: Make sure nothing is blocking the doors from opening, either inside or outside the van.
* Check the door strikers: The striker (the metal part on the van body that the latch engages with) may be misaligned or damaged, preventing the door from opening.
* Check the child safety locks: Some vehicles have child safety locks that prevent the doors from being opened from the inside. Check for a switch or lever that may need to be disengaged.
* Check the wiring: If the power locks are not working, there might be a problem with the wiring. This would require professional diagnosis.
If none of these solve the issue, you may need to consult a mechanic or an auto repair shop.
