Well... pop your hood, look in the right far corner and notice the fusebox... open the lid and read the fuse legend (located on top of the lid). In the bottom right corner you will see the A/C fuse and directly above that it's the FWD fuse. Check if there is one in there... if there is, this means somebody forced your SVX to FWD. If there is no fuse then something else is wrong.
