Air conditioner


There are several switches involved in an ac system . There is a high pressure switch that turns off the compressor if the head pressure is too high (blocked system-excessive gas qty) and a low pressure switch that switches off the compressor when there is insufficient gas -(leaking system)/ Next some systems do not work unless the blower and the ac switch are both on ( prevents ice forming on the evaporator coils from lack of air flow ). That is the electrical side of things . Next there is a TX valve that allows the liquid refrigerant to become gas in the evaporator ( producing the cold air) that can become blocked . There is a thermostat that is attached to the evaporator fins that will shut off the ac compressor when the cabin temperature has been reached. Next there is an air/dryer accumulator that can become blocked from moisture and dirty oil that will affect the operation. Well that is all the points that can cause problems.
How does it work . The system is full of refrigerant gas that boils off at a very low ambient temperature . The compressor compresses this gas and turns it into a liquid refrigerant in the condenser (In front of the radiator ) This liquid is pumped to the TX valve which releases the liquid into the evaporator coil and as this area is in vacuum from the compressor sucking the gas ,the liquid going from a liquid into a vacuum boils off from the heat in the car . This cools the air in the car . The gas is then sucked back to the compressor where it is again converted back to a liquid . As you can see ,any items that are not working properly will cause problems because the circulation of the gas has to follow a set procedure or the compressor will shut down. Best advice is -if you having ac problems then take it to an accredited ac specialist and have the system tested for gas and leaks.

AC hoses leaking


The condensation will be mostly forming on the suction line to the compressor . It is the moisture in the air forming water droplets when the air hits the cooler pipe. The refrigerant boils off inside the line because of the low pressure cause by the sucking action of the compressor and this boiling off reduces the temperature of the line and so the condensation forms . It will be the larger of the 2 pipes and if this condensation is causing concern then there is a form tube that you can get from the rubbers shops that you can wrap around the line and this insulates the line and so the condensation will not form. When the system is working properly you will notice that the smaller line will be quite hot as the compressor compresses the refrigerant back into a liquid so that at the TX valve in the evaporator(inside the car) releases the liquid into the vacuum created by the compressor sucking on that line. The heat in the car helps boil off the liquid to gas and in doing so removes the heat from inside the car . As it is doing this there is condensation forming on the evaporator fins that drains off out a tube to outside under the car ,hence the pool of water on the road as you drive off.

2001 s500 airmatic problem car air compressor stays on long and the car is very high


check the relay for the airmatic compressor it is on the passenger side in the engine compartment right next to the hood hinge. pull the cover off and its the 3rd relay back from the front. the relay might be sticking closed but have it checked before it causes the compressor to burn itself out

My car boils water and takes out hot air


Hi, do you mean that your cars cooling system boils and a lot of steam escapes? This could be caused by a number of things and I would never attempt to diagnose an engine problem without looking at the vehicle in person but most likely from your vague description I would suggest that you have either a head gasket blown or your head is cracked, both of which require experienced diagnosis and rectification. Make sure your radiator is full of water (only fill when cold, never when hot) and take it to a reputable mechanic who will tell you what is wrong. I hope this helps

Car dies some times when heater is turned om


If you have air conditioning, I'd check the A/C compressor to rule that out first. It has a very real potential to be going bad. The clutch on the compressor stops putting drag on the motor causing it to stall. Any high pitched squeal just before stalling? I know you're talking heat, and I'm talking A/C I realize that. Happens a lot on Windstars I've dealt with.

Air conditioner isn't blowing cold air


Could be a number of things...electrical connections causing the compressor not to run. Turn on AC and turn your thermostat all the way to cool...now visually check to see if compressor is engaged and not just free wheeling. Most likely you lost your refridgerant due to leak in the system...would need to find leak and repair then have your system re-charged with refridgerant. Best case scenario...your system just needs a charge of refridgerant due to not having enough.
