ACDelco 15-51343 GM Original Equipment Air Conditioning Refrigerant Pressure Sensor

Q: I have a hummer h3 2007.. a/c is not cooling ..can someone tell me where is this sensor locate ? i can't find it.. (explain with details)

Start at the A/C-compressors output line which is leads to the-high-pressure charging port,and follow it with your hands,if you cannot see it the entire length of the line. The switch has an electrical-connection, which should help you identify it. The High pressure line on your gauge set will only fit the high pressure fitting, which will help you identify the line. if you are new to this, the best thing you can do is to find a YouTube video which covers this procedure, unless_you have a manual for your vehicle, which also describes the procedure. The high pressure fitting on your gauge set or the gauge on your recharging bottle will only fit the high side charging-port.

Q: Can this be used for a oil pressure sensor as well

This is a cycling switch for AC systems only

Q: Can you tell me where its located on a 2014 gmc seira 5.3 lt. 1500

On my 2014 Silverado, it was on the passenger side of the engine. Had to remove the fender liner to get to it. Maybe different on a GMC.

Q: Is this the high side pressure sensor for the a/c?

Yes. The old one unscrews and the new one screws back in its place. A valve in the socket prevents gas from leaking out. This is a combination switch and sensor, which controls the compressor coming on and off. It is typically located on the high pressure line leading from the compressor to the high side charging port. See my review posted on January 4, 2021 for more information. If there is insufficient gas of the correct type in the system, the compressor will not come on; likewise if the electromagnetic clutch on the compressor is rusted out or just broken, a new switch will not cut on the compressor. If you are new to this, watch a few YouTube videos on diagnosing and recharging your car's A/C system; reading a service manual will also help.
