I want to charge my AC but don't know how the pressure changes with the ambient temp.
As the temp rises so do the pressures high side and low side, at 100 degress outside low side pressure should in the area of 41 to 57 psi depending on hunidity.

SOURCE: I need to know how to jump the ac low pressure to get my ac compressor to come on.
If you look on the low pressure side of the AC system you will see a plug that is incorporated in to the line. It will have two wires leading to it. Remove the plastic clip that attaches the two wires to the sensor and use a short piece of wire to connect the two terminals in side the plug by putting the ends into the cap. This will bypass the low pressure sensor and allow the AC clutch to engage and begin to cycle again. Remember this low pressure switch is there for a reason. If you don't add more r-134 to the system and allow the AC compressor to cycle you will destroy the compressor. You need to charge the system when you bypass the low pressure switch and get the system up to full charge status and reconnect the switch.
SOURCE: AC Low Pressure location on 2004 Chevy Suburban
You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the
vehicle. You can also follow the compressor line to reach the port.
The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.
To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with
plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.
Regards.

Look for the accumulator(silver can a/c lines go to) on the passenger side of engine area. The Low side charging port cap should be on the side of the accumulator.
SOURCE: Heater only works on passenger side.
there is a motor actuator that moves these doors for hot and cold, two separate ones for either side. the motor unit for drivers side is no good and needs new one. replace this and all will be good.
