I have a 2001 Xsara estate HDi 90BHP. Recently the rear wiper stopped working. Now when I open the boot using the catch, the wiper moves a little. Also when I turn on the ignition or turn on the rear wiper or the side lights, the boot lid tries to open (and sometimes does release). The wiper does work most times, but it runs more slowly than previously and rarely stops at the end of its wipe (with the boot now released!). Anyone had this problem or have any ideas? Dan
