Boot Is Not Opening C4 Hatchback 55Reg

[arak81]

Hi guys,

 

Since this morning all of a sudden my boot stopped working. I can hear the clicking sound when pressing the button but boot is not opening. I have managed to open it  from inside and sprayed some WD40 but still it is same. has anyone got any idea what could be the wrong with it? thank you.

A common problem on the C4 is the wires between the body and tailgate can break in the rubber tube top left as you look with the door open. You may also find the rear wiper and any lights on the tailgate may not be working.

Thanks paul.h

 

Rear wiper and all the rear lights work fine. Cant's find any wire broken too.

I opened the rear handle and cleaned the part and assemble  them back but still no luck...so I don't know if it is wrong with the part..has anyone ever had this problem and how did they sort it out?

This topic starts as a C5 one but then becomes a C4 one which is worth a look http://www.citroen-owners-club.co.uk/citroen/topic/23731-2007-c5-estate-tailgate-door-will-not-open/ For the C4 it was the wiring and the switch. All the switch does is connect the 2 wires to it together so that the supply wire is connected to earth - so if you still have the switch off you could connect the 2 pins together in the electrical socket to it with a bit of wire or a paper clip to simulate the switch. Then if the lock opens you know the switch is faulty, if not then it may be the wiring or a fuse or possibly the lock motor.
