You may have a broken or stuck valve in the compressor. The compressor itself may be worn out. If you replace it, don't forget to flush the system, replace the orifice tube and replace the accumulator. First things first, though. Is the clutch engaging properly?
High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
Low side.
The compressor changes the low pressure gas into a high pressure gas which then has the heat of compression removed in the condensor to turn it into a high pressure liquid.
Always to the low pressure side. The low pressure side fitting is normally near the dryer ( large silver canister).
150 high 75 low
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
Red is the high side.. The low side is blue..
Low predsure very high
Because it's the only way to recover it. You recover from the high pressure side, and charge it on the low pressure side.
it is the low pressure side
R134a goes into the low pressure port
The high pressure side is the discharge side. It runs from the compressor outlet to the metering device inlet. The low pressure side is the vacuum side. It runs from the metering device outlet to the compressor inlet.
