I do not know if it the same as the 99 but the low port is the one further away from the radiator on the passenger side of the car.
Engine compartment, on passenger side. Back box by the water reservoirs.
On a 1993 buick regal it is on the side of the radiator.
under the cover, right side. there some letter on the sensor <ab?>
On a 1993 buick regal it is on the passager side of the radiator. Hope this helps
It's on the firewall, back center of the engine compartment. There is a silver colored piece of metal tubing, the low-side port is on this tube.
On the side of the dashboard on the Passenger side.
Should be at the firewall on the passenger side
On the upper firewall on the driver's side
It's near the firewall in the center where the low side tubing returns from the evaporator.
I'm assuming its like other buick regal models, around the passenger side windshield wiper.
At the rear of the motor, on the passenger side.
