I have a Xsara Picasso, and the boot intermittantly won't open when the boot switch is pressed. It also sometimes (not often) opens on its own. I have checked the latch and switch thoroughly, yet neither is at fault. It is clearly some kind of logic fault.....the switch reliably operates, and when alkl is well a 12V pulse is sent to the latch (for circa 2 seconds). Sometimes, (when all is not well), no pulse is received at the latch. And I had so hoped this would be an easy fix, but that's as far as I got!! Any advice would be well received!
Thanks,
Peter
