My rear door on my 2004 Volvo XC70 does not open from the outside only from the inside how to fix?

SOURCE: Volvo s40 rear doors wont open inside or outside

There is a child safety switch on the rear latch assembly that prevents opening from the inside handle. This switch may be on. Check your owners manual for more info.

SOURCE: how do i change cabin filter for 2004 volvo xc70

it is located underneath the passenger floor under the dash. Take off the side panel on the side of the center console, then take off the cover shield underneath the pass side dash. Once you remove the two pieces you can see a black cover. Its 3 bolts T25 torx will do the trick. Drop the black cover plate and the pull out you cabin filter. Put back together in reverse order.

the handle might of broke internally, theres a rod and a clip that gets attached to the handle. i would take the door panel off and visual look at the latch mechanism and the rod that goes from that to the outside handle

SOURCE: volvo xc90 rear hatch door closed and won't open

Hold the hatch hard closed into its frame whilst pulling on the release handle. The mechanism on most cars consists a grab/release on the door and a simple metal hop at the bottom of the frame. Over time the hoop can become loose and move slightly inwards each time the door is shut. The door seal rubbers push back on the door surround putting a lot of tension against the grab/release mechanism preventing it from releasing. By pressing on the door and compressing the rubber surround you will take the pressure off the release mechanism and allow it to open when you pull on the handle. Once the door hatch is open, loosen the mounting bolts to the metal hoop and move it out about 10mm. Tighten the mounting bolts. Shut the door gently as a trial close and check for security of fit. If very slack, ease the hoop inwards a couple of millimetres. When happy, tighten the mounting bolts securely. draw around the hoop mount with indelible ink so if it moves in future you have early visual warning and can remount it easily

As far as I am aware this has to be performed at the dealer, or at least by someone who has access a fairly current version of Volvo's VIDA program
