I've followed the instructions in the Powerful video and still cant get the front interior door card off. I can undo all the screws lift it away from the window BUT something keeps it attached. Am I missing something has someone else done this found the same problem and overcome it. Geoff

Is there nothing in the wiki that would help  Last night I lay in bed looking up at the stars in the sky and I thought to myself, where,s the f**king ceiling!!

There is a plastic retaining clip on the back of the card that locates into a metal sleeve about halfway up the card. It's more than likely to be this if you can move the card yet it still feels tight in the centre.
A good sharp tug normally frees it. Take it steady around the window switch panel as this usually needs tilting and pulling rearwards to avoid the tweeter. 2006 4.2 SC
