This one took me 30 mins to find, its at the back of the engine at the center of the firewall (below the windsheild ) . This is where the a/c lines go into the car ( evaporator) its hard to see if your tall . Remove the cap and attach your guage . Good luck.

Ps. Fix the leak first

Where is the low ac suction side located on a 1992 buick regal


First find the A/C compressor, it is attached directly to the engine and has a pulley on it. When you turn on/off the A/C while the engine is running you should be able to locate it by listening for it to engage.

When you find it you need to trace the two metal pipes that come out of it. One pipe is the high pressure side and one is the low. You will know which one is the low side when you find the 'tee' with a plastic cap (both high and low have one).

The fitting that comes with the A/C recharge kit will only fit properly on the low pressure port. Sometimes, but not always the low pressure port has a blue cap.

I have a 99 Buick Regal, my low tire is staying on although tire pressure is right. Any ideas?


open the passenger side door,

There should be a little panel on the dash that covers the fuse panel.

Pull the cover off.

Turn the key to the run posistion.

Press and hold the button in the passenger side fuse panel that says RESET.

The Low tire light should flash 3 times then go out.

It will now have to go thru a re-learn procedure, which will do it's thing while you are driving around. Just make sure all the tire pressures stay at the correct level.

Where do i add r134 on the 99 buick regal , I see to nozzles under the hood one to the right boy wheel shock and the other back center closr to firewall


Closer to firewall is where your low side port should be. Your R134 filling hose quick connect adapter will ONLY fit on the proper "low side" connector port at that location because it is a different size than the high pressure port. You can't put it on the wrong port and get it to fit.

A/c blows hot air on drivers sde


The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.

Where is the A/C recharge port located in a 2001 Buick Regal?


Find your A/C compressor. On the compressor you will see two pressure lines, one small and one larger line.
Pick the larger line and follow it back to the firewall, on that line will be your "low side" charge port for recharging purposes.
Good luck, let me know.

Location of low pressure air conditioning port?


Follow the biggest a/c line from start to finish.Usually the a/c port is located near the firewall.I have seen the port located under the passenger wheel well.There should be a decal that states the type freon on or near the fan shroud,core support or on the under side of the hood.It is most likely to be type r-12.You can purchase an r-134a conversion kit. If you are not a/c certified to use r-12,you do not need certification for r-134a.
