The coupler in the supercharger! It gets worn and the supercharger sounds like it's grinding rocks, it's common rip off saying they need a new unit, and installing a 40 dollar coupler. The blower motor control module located in the passenger floor board is also a common issue, it can go out and make the blower motor stay on even with the car off, or just not work at all. It also seems the control arm bushings wear out quickly, but they can be replaced on the 1995 (newer models have non serviceable units). Also the 95's don't use dog bone mounts, and the lower mounts often go out and need replaced. On the non mechanical side, my doors freeze shut and its scary tugging on that plastic door handle to open them.
A 1995 Buick Riviera wiring diagram can be obtained from most Buick dealerships. The wiring diagram can also be found at most auto-parts stores.

ON THE 1995 BUICK RIVIERA THE HORN IS LOCATED UNDER THE LEFT HAND SIDE FENDER. U WILL HAVE TO TAKE OFF THE TIRE AND REMOVE THE FENDER PANEL. THE HORN WILL BE ON THE RIGHT SIDE OF THE LEFT INNER FENDER.

The 1995 Buick Riviera SC 3.8 uses a 4T60E transmission very similar to the other 3.8's of the era and will physically bolt up to other cars, though the gearing of the final drive in the supercharged Riviera is 3.29 fine pitch, where the others are most often a 3.06, 2.83 or 3.33 none of which are fine pitch ratios. This will cause problems with trans control modules. Hollander interchange lists the 1995 Riviera SC 4T60E non-interchangeable with any other applications.
I would replace the line....ughh
