The low side service fitting is located near the right side of the strut tower (inner) near the fire wall. It is located on the upper a/c metal/rubber hose. The high side fitting is located on the lower a/c refrigerent line to the left side of the right strut tower. Hope this helps
behind the right front wheel well
Passenger side near the fire wall. You can find a diagram of this on the link below. Just follow the "Where is my low side port" icon when you get on the website.
Where is the lowside service port on a 2000 buick century?
im trying to find out where the a/c low side service port is on my 95 buick century
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.
The EVAP Service port is on the firewall on the passenger side, right next to the low side service port for the A/C.
Well if it's the same as the 97 buick Skylark the blue or low pressureAC line is near the lower pressure hose coming off of the radiator... almost right next to it.
This question eluded me when I first got my 1996 Buick, lucky for me when I looked under the drivers side dash I found an access panel open which would not be normally be that way. Inside this panel is the OB2 port.
The low side ac port is mounted close to the firewall. While its beside of the high sided port, the sizes are different to prevent accidentally connecting to the wrong one.
The low pressure service port for the AC on a 1998 Olds Aurora is located on the side of the accumulator. It is at the back of the engine compartment, on the passenger side.
Its located on top of the compressor................
The service port will be located on the accumulator, the large silver can-shaped device underneath the hood. Inserting freon into the accumulator without the proper gauges measuring high and low pressure can damage the compressor and its components.
