Do the Drivers side and Passenger side have separate "Heat/Cold" controls?
If "No" then I'm at a lose to explain this one.
If "Yes" then it may be that the controls are malfunctioning. It may be that the control switch/rheostat may be malfunctioning and need to be replaced or that the thermistor (the electronic device used to detect the temperature) on one side or the other is malfunctioning. etc. etc...........

I have a 1995 Buick Regal Custom Sedan, and just today I fixed a similar problem with my heater. Hot air would come out the passenger side vents, and cold air would come out the driver side vents and the rear seat vents under the seats. I found the problem was a connection to the electronically controlled ventilation door was not connected. If this is the case, you may want to check those. The heater core will not heat cold air that is moving at 60 miles per hour, which can cause the cabin to become quite cold. !

It's located under neither the passenger door on the drivers side. it is about a foot in underneth the vehicle.
Should be at the firewall on the passenger side
At the rear of the motor, on the passenger side.
On the side of the dashboard on the Passenger side.
I'm assuming its like other buick regal models, around the passenger side windshield wiper.
passenger side floorboard panel
tire size and presure are always on a sticker on drivers door or drivers door post.
The fuel filter on a 95 Buick Regal should be located on the frame, probably on the drivers side in front of the fuel tank. It is an inline type and is easily replaced.
should be on the passenger side right along the fire wall
the blower motor is under the dash on the passenger side of the car
Passenger side, under the alternator, towards the firewall.
Look on passenger side rear of engine
