Citroen C4 failure

If you stop working the rear windshield clean or it does not work to open the trunk.
Solution opens the door from the inside with a fine screwdriver in a small hole that carries the lock.
Lush the cable rubber on the left side that crosses the porton to the abitaculum cut it from top to bottom and you will see that all cables are chopped or cut, typical failure of the C4.
You must cut a metal flap that carries the rear door,
thus making the largest hole and place a water sleeve or something similar as a foundation.

I cut all the cables and made them longer to not have problems because the wiring seems to be short.
