Hi, - Citroen C3 Picasso 2014 Exclusive - My back passenger (near side) door has decided not to open from the outside. Occasionally it does, but reverts to not again. I can always open from inside. Wo.
Usually the fix is to stand near the driver side rear tire, then press and hold both the Lock and Unlock buttons at the same time (for up to 30 seconds). If successful, you'll hear the horn honk at you. Then your FOB will work again as expected. Give it a shot, doesn't take long and its free!2. A loose or corroded terminal in cavity A2 or A3 of the IP fuse block connector C3 (black connector) 3. A broken light blue or white wire between the BCM and the IP fuse block. 4. A failed rear door lock relay in the IP fuse block. This relay is soldered onto the circuit board and cannot be serviced. Page 46 of the online manual. You have to lock the driver door with the key, take out black plugs on the passenger doors to slide a latch and diconnect the battery to lock the boot. A bit of faff but it can be done. Assuming you have a spanner to diconnect the battery it's a 5 -10 min job for regular person. Popular posts on the C3 forum. Citroen C3 Central locking stopped working! [SOLVED] Help! I can't log in. As the Citroen C3s get older some of the less expected parts need changing. The rear seat belt is one of those. They can get slow to recoil and the buckle gets jammed in the door shut. Damaging paintw. Unscrew the cap off rear upper corner door panel locks. These don't have a rod attaching them to the handle and unscrew separately from the door handle. Pop the door panel off after you've removed everything. Gently pry on the bottom edge of the door panel until it releases. Pull out and up to completely remove the door panel. Smni.
