your condensor is clogged up, or your condensor fanmotor is not working, or your compressor struckup due mechanical problem inside of your compressor.
It could, the computer will disengage the ac compressor if the engine temp is too high.
Compressor problems but sounds the opposite of what the symptoms are usually. Repace compressor and check for leaks. Compressor problems but sounds the opposite of what the symptoms are usually. Repace compressor and check for leaks.
High voltage and low resistance would cause high amps. E = I R or I = E/R. PS E would be electromotive force measured in volts. R would be resistance measured in ohms. I would be current flow measured in amps.
Was the voltage to the compressor clutch checked? Not knowing how thorough the under-hood check was, it sounds as if the compressor is not engaging. The causes for that are varied, but it is an electronically controlled event.
Inside an air conditioner compressor is a motor with two windings: a high-current coil called Start, and a low-current coil called Run. Both windings are connected to each other at a junction, aptly called the Common terminal.
A window already has a casing around it to protect and allow condenser venting. An air conditioner that is made for a sleeve has no protective shell around it, so if you put a window air conditioner in a sleeve you will not get good air circulation from the fan that cools off the condenser. That will result in high pressure at the compressor, high temperature at the condenser and high temperature at the evaporator. This will result in poor cooling and probable compressor failure which will allow you to go out and buy an air conditioner that is designed for a sleeve.
On any automotive A/C system there is one basic rule. The line that leads from the compressor to the interior of the vehicle is always the Low side. The line that runs from the compressor to the front of the vehicle is always the high side.
The electric fans used to cool the engine are designed to switch on to full speed when the air conditioner compressor is being used. When you turn on the heater/defroster the air conditioning compressor also turns on to help remove moisture from the air. Since both when heating or cooling your car the air conditioner compressor is working the fan will be running at high speed and makes more noise.
It's a cycling clutch compressor. It disengages to keep system pressure where it should be. When it reaches the high point, it disengages. Then it engages again when it reaches the predetermined low point.
Too much refrigerant can do it, yes. System pressures get extremely high on both sides of the AC system when it is overcharged.
It is difficult to determine the different pressure ports on your air conditioning compressor without knowing the make and model of the automobile. In most cases the low pressure port is on the right hand side of the air conditioner compressor.
The low pressure port on any A/C system will be the the line running from the compressor and going into the evaporator in the passengercompartment. The high-pressure port is in the line coming from the condenser in front of the radiator going to the compressor.
