I just recently purchased a used 04 Saab convertible, and I have already had 3 issues w/ the convertible top not going up or down. It's been taken to the dealer once (..about 2 weeks ago), and it was supposedly fixed, but now it is acting up again. How can I raisethe top manually until I can get my car to the dealer again? When I press the button to raise/lower the top, it will come up half-way, but stop. I am so aggravated by this issue. Any help would be greatly appreciated.
