1) Compressor failure, check Hi side to see if readings are close. 2) Make sure electric condensor fan/rad fan is coming on when a/c is on, if clutch fan make sure it is working properly to keep condemsor head pressures down.
3) This is a very common problem on Dodge vehicles. Try draining low pressure port. Get the pressure out. You can do this with a screw driver. Push in on the low pressure port where you put coolant in the line. Just like you would take air out of a normal bike tire to deflate it. When you do this be very careful due to high pressure in the line and the collant coming out could freeze your hand on the way out. Very simple process. I suggest you be at least 18 to try this. The safest way is to take it to a garage obviously ut times are tuff so why not just try it yourself and learn. good luck

Why do southerly winds occur on the trailing side of high pressure region?
Most weather systems in the temperate latitudes move from west to east. This makes the west side of a system the trailing side. In the northern hemisphere, high-pressure systems rotate clockwise, resulting in southerly winds on the west (trailing) side.
If your back is to the wind in the northern hemisphere the high pressure area is usually on your side?
Yes, that is correct. In the northern hemisphere, winds tend to circulate clockwise around high pressure systems. So, if your back is to the wind, the high pressure area is typically on your side.
What is R134a low pressure and high pressure system off?
In the low-pressure side of the system, R134a is a gas with low temperature and pressure, typically around 30 psi. In the high-pressure side, R134a is a high-temperature, high-pressure gas, usually around 250-350 psi. These two systems work together to transfer heat from the inside of the vehicle to the outside, providing cooling.
which areas can be used for as the differential pressure transmitter?
1: Guage pressure measurement by supply the HIGH side and venting the LOW side to the atmosphere 2: Measurement of level of open tank by connecting the impulse line at the bottom of the tank to HIGH side and venting the LOW side 3: Measurement of level of closed tank with liquid and Gass interface by connecting the the impulse at the bottom of the tank to HIGH side and the impulse line at the top of the tank to LOW side of the transmitter capsules 4': Measurement of Vacuum by connecting the impulse line in LOW side and venting the HIGH side to the atmosphere 5: Measurement of absolute pressure by supply the HIGH side and blinding or blocking the the LOW side

What should be high side pressure in ac?
You need to specify what kind of system. Automotive AC systems and home AC systems use different refrigerants. That, along with the temperature/pressure relationship and ambient air temperature, all factor into what your high pressure (and, consequentially, low pressure) side should read on your manifold pressure gauge.
If your back is to the wind in the northern hemisphere the high pressure area is usually on your side?
Yes, that is correct. In the northern hemisphere, winds tend to circulate clockwise around high pressure systems. So, if your back is to the wind, the high pressure area is typically on your side.
What makes the low pressure side of ac systems fluctuate?
It happens in normal operation. Most vehicles have a cycling clutch system, which cuts off and on within a specified system pressure range. When the pressure gets to the high point, it cuts off, then cuts back on when the pressure gets to the low point.
What does high-side and low-side mean with respect to car AC's?
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.
Is the suction line the high side?
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.

On newer R134a systems, the LOW and HIGH side service fittings are quick-connect style fittings. The LOW pressure fitting is SMALLER than the HIGH pressure fitting.
What color is the high side on a pressure gauge?
Red is the high side.. The low side is blue..
What part of the refrigeration system changes the high pressure side to the low pressure 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.
What is suction and discharge head?
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.

LOCATE THE SERVICE FITTINGS Next, you need to locate the service fittings on the A/C system. There are two: a LOW side fitting and a HIGH side fitting. The LOW side fitting is usually located on the suction hose or line that goes from the accumulator to the compressor. The HIGH side fitting is located on the line that goes from the compressor to the condenser.
