Hi Bluenose
If you're struggling to get the trims that run down the windscreen (A pillar I believe they are called), they are a right pain. There's some black clip that must be rotated 90 degrees at the top, and if memory serves me correctly, the bottom too, before the trim effortlessly detaches. Getting this off is a faff and took me ages. It's important however, it keeps the trim in place if airbag deploys. Stops it hitting you in the face at high speed.
Would getting the above trim off help at all? If so, it will come off if you persevere. Maybe you can see things a bit more clearly. If your fitter did what I did, I fixed the power cable in place at this point, so the air bag would not deploy with a thick cable running in front it. Could be dangerous otherwise.
Any clues here?
Sorry I can't be of much further help.
