My son has asked me to look at a problem with his 2007 Xsara Picasso. The driver's side rear door electrics aren't working - i.e. the windows and the speaker. I have examined the door loom connector at the door and it seems sound. My theory is that there is a connector at the other end which has been disconnected? Does that sound plausible? Any ideas where I can locate it? Thanks, nolly53
