    where is the low side service port?

  • chaywoo May 11, 2010

    sooooo, where is the low side port? is it on the driver side? next to master break cylinder? has little green cap that says hand tighten only.. cant find it on the passenger side... And for all those people asking correct pressure,, one thing you can do is charge around 35 psi or till compressor runs 90+% of the time while engine is idle, and ac is on full blast in the car..
    Thanks!

    That actually depends on the ambient temperature.

THIS IS DEPENDENT ON AMBIENT AIR TEMPERATURE , THAT IS TEMP OUTSIDE NEED TO GET TEMPERATURE PRESSURE CHART TO DETERMINE THIS NUMBER , ALSO LOW SIDE OR HIGH SIDE , LOW SIDE PRESSURE IS THE ONE I USUALLY USE TO ADJUST CHARGE , BUT AS I SAID IT IS DIRECTLY RELATED TO AMBIENT AIR SO THERE IS NOT A GIVEN NUMBER SHOULD BE ABLE TO GET CHART @ AUTO SUPPLIER OR JUST ASK ONE OF YOUR AC PEOPLE IF THEY CAN MAKE YOU A COPY OF ONE .

2006 Ford Fusion Air Conditioning compressure not turning on.


Thats pretty high if the system is not running. Average pressure on the low and high side should be near outside air temp.
Normal low side is 30-40 psi and high side is 200-250 psi when the system is running and the freon charge is full.

Cant find the low port line on ac on a 2002 ford expedition i looked on all ac lines there is a green cap above the brake booster but that cant be it not a steel line its plastic and o


Hi, if your charge hose fits on the fitting under the green cap, then that is the right one. Plastic can handle the pressure on the low side. The low side port is always on the line that goes from the firewall to the compressor. So you can trace that line across the firewall and on to the compressor to make sure.

When i turn on the a/c,the compressor does not work


CHECK REFRIGERANT CHARGE. USING A MANIFOLD GAUGE SET. HOOK MANIFOLD GAUGE SET TO LOW PRESSURE PORT AND HIGH PRESSURE SIDE PORT. LOW SIDE PRESSURE SIDE SHOULD HAVE 25 - 36 PSI AND HIGH PRESSURE SIDE SHOULD BE 178 - 237 PSI. IF LOW SIDE PRESSURE SIDE READ BELOW 20 PSI THE LOW PRESSURE SWITCH WILL NOT TURN ON THE AC COMPRESSOR CLUTCH NEED TO ADD LITTLE MORE REFRIGERANT. IF REFRIGERANT LEVEL CORRECT CHECK AC COMPRESSOR FUSE AND RELAY.IF POWER GOING TO AC COMPRESSOR CLUTCH YOUR COMPRESSOR CLUTCH HAS OPEN WINDING. AC COMPRESSOR CLUTCH NEED REPLACING.

A/c recharge what is thew psi for refrigerant


Below are normal car AC pressure readings with 134A.

Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI

Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI

Normal high side reading ranges from 200-350 PSI
Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience.

If normal gauge readings are obtained and the vent air is cold – STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system.

Thank you for using fixya and be safe.

I Have a 2000 Expedition 5.4, atempted to charge the ac. I was getting a preasure reading but no freon would go into the system. When the compesor cicks on i get a reading of about 30 psi when it goes off...


Add more freon, should have a low side reading at about 30-35psi at about 1500 rpm and stay there, if it drops low pressure switch will cut a/c compr. off.

What is the a/c operating pressure's of a 2001 expedition 4.6


Normally, when the AC compressor is engaged the low side should read between 25 and 50 psi. and the high side should read between 130 and 175 psi.

2002 ford expedition air conditioner needs R 134 refrigerant. I cant seem to locate the service port.


The low pressure valve on the 02 expedition is located on the accumulator on the passenger side fire wall. The accumulator is underneath the battery relay and a grouping of wires. Had to squeeze hand underneath a heater2_bing.gif hose and an a/c line to remove cap and hook up hose. Nothing has to be removed to locate the valve just a little touchy feely. Valve faces a 45 forward toward the engine.

Ac wont get cold after adding refrigerant


To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI Normal high side reading ranges from 200-350 PSI.
Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Both low and high side readings are lower than normal, this indicates a cars AC system is low on refrigerant and is under-charged. If both low and high side readings are too high, this indicates an overcharged system - too much refrigerant. This also can indicate that the condenser fan is not working, is too slow or the car is overheating and heat is transferring from the radiator to the condenser.

When the low side goes so low that it’s reading shows it is in a vacuum, the most likely cause is a bad expansion valve or blocked orifice tube. Another possibility is a restricted condenser. Blocked condensers are not as common as they used to be but if a compressor fails and comes apart inside the remnants can end up in the condenser causing it to restrict the flow of refrigerant. 

When the compressor clutch is definitely engaged and the low side is high and the high side is low, the most likely cause is that the compressor is failing - it is not pumping sufficiently. Rarely an AC clutch could be slipping but usually this will be accompanied with a squeal or chirp.

Hope this helps. If the compressor did come on and pulled the R134a in to the system, you may still be low or you may be over charged. With out any pressure readings it's had for me to say what is the problem. You could also have a bad orifice tube ( expansion valve) Good luck and hope this helps.

1999 ford Expedition ac problem


Rick, u will need to take your car to get serviced. If your ac is not working properly it might be something inside that needs to be looked at. You might need to replace your heater box.
