Re: Driver folding wing mirror. These can become unsynchronised between the mechanical position and the memorised electronic position, especially if the mirror has been physically moved out of position (knocked) for example. 1) Move the mirror manually (by hand) all the way in (closed) and then all the way back to open position. I have the same problem - 2014 C4 Grand Picasso. When I press the tailgate open button on the key, it unlocks, but does not raise. I can manually open it, but it takes some effort to lift the tailgate. Pressing the button on the tailgate to close it - I just hear 3 short beeps and no movement. Citroën Grand C4 SpaceTourer. Citroën's Grand C4 SpaceTourer, formally the C4 Picasso, has been designed with families in mind. This 7-seater MPV comes with three ISOFIX points that make fitting child seats a breeze as they're easy to access, and the lower floor height coupled with broader door openings means the kids can climb in by themselves. Citroen C4 Grand Picasso Boot Won't Open - YouTube © 2023 Google LLC A common fault on the Citoen Picasso range is that either the handle assembly breaks or the microswitch fails However it now works but it only works when you press the left hand side of the handle where as - before it went in it worked both on the left and right side of the boot handle, kinda like a see saw effect. Thinking of getting it swapped on its next service, though I am told it is a citroen only part and valued at £19.99 to buy. iNJ5vt.
