mate ive got a 96 seca. I had the same issue too. you'll need to replace the thing-a-majigi that keeps the boot up. Keep in mind the boot on these hatches are bloody heavy. So its a common issue on these rollaz.
I think their called gas struts or dampers. They are the two long black bars that keep the boot lid up on each end.
Probably just go to autobarn for a new pair.
hope that helps

i vote this.... the best reply to a thread ever.
