Anyone know what the high and low side operating pressures should be on a 2003 Ford Focus air conditioning system?
Stevenwright
The low side will be somewhere in the neighborhood of 30-40 PSI, depending on abient temperature, temperature in the car, and atmospheric pressure. The high side will be around 150-200. Maybe a little higher, if it is a really hot day.

What is the High and Low side pressures of a 2000 Toyota air conditioning?
It isn't that simple. Pressures will be based on a number of factors, including ambient air temperature, elevation, and humidity. The pressures should read in accordance to the pressure/temperature chart for an R134a system.
How do you determine what suction pressure should be in R410a air conditioning compressor suction line?
Read the charging chart specific to the unit. Not all 410A machines will operate at identical pressures in identical conditions.
How does one add freon to an air conditioning unit?
Adding freon to an air conditioning unit should only be done by a certified technician. It is in fact illegal for anyone to add freon to air conditioning that isn't properly certified, so one would add freon by calling in a certified technician to do it for them.

How do youTroubleshoot AC on 2003 Explorer Sportrac?
you will need a set of guages to do this, you will need to have the vehicle on max a/c with the windows closed. some visual indicators are oil around the joints on the air conditioning compressor mounted on the engine, or around the hoses and their seals. available from auto stores, and places such as target, walmart etc... are cans with pre-mounted gauges that give recommended operating range, typically 30-45 psi on the low side (the lager hose that is cold to the touch) DO NOT CONNECT TO THE HIGH SIDE CONNECTIONS TO INJECT COOLANT OR OIL! the high side (small hose) should be warm or significantly hot to the touch, and the low side (larger hose) should be cool to the touch. while the low side and expansion chamber shoudl be cold they shoudl not be building ice, if so your pressures are incorrect. if you have a manifold gauge set you can monitor the pressures on both sides of the compressor, and with recomendations from your local a/c parts distributor they can advise you on propper operating pressures for your specific vehicle.

What is the correct operating pressures for R134a refrigerant in a 2003 dodge ram truck air conditioner?
The make and model doesn't matter - the correct pressures for an R134a system in one vehicle is the same as the other. What the pressures are supposed to read can vary greatly. There's a little something called the 'pressure/temperature' relationship. In short, the ambient air temperature and humidity level are going to impact what the correct system pressure should be. So, depending on what the ambient air temperature and humidity level is, the correct operating pressure can be anywhere from 28 - 60 psig on the low side, and anywhere from 130 - 350 psig on the high side.
Do both fans always run on a 1990 Honda civic?
The fan attached to your radiator should come on intermittently, which means when the engine reaches operating temperature the fan with turn on an off every few minutes or so. The other fan is for your air conditioning. It should be running constantly if your A/C is on.
