why not scan the PCM first (OBD2) port for DTC errors
from right door. front.? that be 2nd step after fuses.

How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)

Antennas in the passenger compartment and cargo compartment

An antenna in the rear bumper

Quick lock motors in the lock units in the side doors

The remote keyless entry (RKE) receiver receives a signal from the key

The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)

Key-in switch.

Switch in door handle and lock button on handle .
If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.

sounds like the doors that open and close that direct the air are jammed, or are not receiving a signal. Have someone run a code check which should tell you. May just need to have a faulty code erased or...$$$ repair by Volvo.

{: ) Check the ECC fuse10amps at the IP fuseblock. If okay, it's most likely that you will need to replace your liftgate latch. The latch is inside the rear door trim, but since the rear door is stuck closed, it must be opened manually. I suggest you leave that part to the door masters, they know exactly the right technique. If you do it yourself, theres a chance you can break something.

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

Make sure you have a fresh battery. If battery is good, then the receiving module in the rear view mirror may be faulty.

And of course: make sure you have the right keys......(joke)

You have 4 doors with 4 electronic modules. Front doors have "master" modules and rear doors have "slave" modules. Master modules are called DDM and PDM - Driver Door Module and Passenger Door Module. These modules communicate directly to the main computer via CAN bus.

But module in the rear door communicates only with the module in the front toor on the same side of the car via LIN bus.
So if the CAN communication channel is broken (wires may get broken where the doors are attached) then on that side of the car doors will not lock/unlock anymore, interior lights will not turn on, windows can't be opened and closed anymore from the remote control on that side of the vehicle. You may just repair the wires.

The other, expensive option is, that DDM or PDM electronic module is dead. Then take it to the shop for repair with the new module...

should be only 1 fuse ,but look to see if thete is another fuse in the fuse box, also make sure the wiring that goes into the mirror is not a loose connection ,follow it as far as possible under the dash and thru the side of the car into the door[ at this area especially] wires sometimes get crimped or broken. Good luck !!

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.

hi jim,

you need to open the door panel, after removing the panel, raise up your window completely and you can see the nuts or bolts that are holding your door handle.
