you buy a new car!
The 1996 Buick Riviera Supercharged is designed to run on premium gasoline with an octane rating of 91 or higher. Using premium fuel helps optimize the performance of the supercharged engine, providing better power and efficiency. While it may operate on regular fuel, doing so could lead to reduced performance and potential engine knocking. It's recommended to use premium fuel for the best driving experience.
In the 1998 Buick Riviera, the AC fan switch is typically located on the center console, integrated into the climate control panel. It features various settings for fan speed and temperature control. You can access it easily while seated in the driver's position, allowing for quick adjustments while driving.
sounds like you need a new dimmer switch, or there is a loose wire

Lots of luck trying to find one - they made 2 types - XAB and XBB There will be a tag, under the engine(trans) in about the center of the car to tell you which one you have. The dealer told us they are NOT interchangeable! However, they ARE interchangeable. The only issue would be that the XAB trans is not as stong as the XBB, specifically the sprag clutch. So while The only other cars produced with the XBB trans was the Buick Regal GS (supercharged), and the Buick Riviera (supercharged). The XAB appeared in all W-Body vehicles GM made, but if the engine isn supercharged, it will be a 4T65e NON-HD (as opposed to the 4T65e-HD in the blown cars). Without the HD option, the supercharged 3.8 will obliterate its bands and clutches, among other things.
Out of gas
No.
I have a '96 Riviera and if they have the sensor for nighttime driving like mine do you cannot drive with the lights off if it is dark, but you can push the knob bellow the light switch all the way to the left where it says Lights Max or something like that. this will turn the lights off while car is in Park, at night otherwise the lights should stay off in the daytime
The OBD port on a 95-99 Buick Riviera is directly underneath the steering wheel kick panel, look for a small sliding door up under the dash. One odd thing about the '95 riviera is that while the plug for the reader is an OBD II form, the computer is actually only OBD I compatible, it has come to be known as an OBD 1.5. 96-99 are all fully OBD II.
E-body same as Eldorodo and Toronado which are front wheel drive, while the riv rear wheel.
Area where your left foot rests while you are driving
Happened to me .. it was the crank sensor. Pretty inexpensive to fix
