I bought a 93 Aero cabriolet less than a year ago. Since then, I have had several minor troubles and one re-occuring big trouble. The door lock motor malfunctioned and wouldn't lock. needed replacement. Passenger window became misaligned or something and wouldn't close after putting the top back up. The big trouble, is the hydrolic oil tube in the top broke, spraying oil into the top and dripping all over the interior. SAAB replaced the top and rear seat with new parts along with replacing the broken part. Last week, the same tube broke again. Has anyone else had trouble with electrical things or the top?
