Close the slide. Stand on the driver's seat and look at the seal behind the interior trim board. On my 07 Vectra the rubber had "pulled away" from the back of the trim board and needed to be re-fastened with some really good double sided tape. On mine the water was getting through the rubber seal right behind the trim above the microwave, just like yours. My double sided tape did not last long and when I was at Forest City I bought a roll of "sticky tape" (they call it snot tape) to replace the double sided tape. I had to install it "blind" as you have to attack it to the back of the trim and you cannot see what you are doing but if I recall you really are just sticking the rubber in the corner between the topper and the trim. Worked for me for several years.
