SOURCE: AC Problems

If there is no gas in the system it as you pointed out the low pressure switch will shut the power to the clutch in the compressor off. your pressureswitch should be located near the dryer at the front of your Benz. You could try and bridge it to see if the compressor engages, how ever DO NOT try and keep it engaged without gas in the system or you may find yourself having to change the compressor again.

You could need a recharge of freon or your A/C pump is bad. You can go to your local garage and have them recharge with an aftermaket freon kit or the dealer and have them put it on an a/c machine and really diagnose the problem

SOURCE: ac not working on 2004 s430

If you have the hood up stand outside while someone activates your air off and on and see if the clutch on the compressor goes on and off while they activate the switch. If that isn't it the it could be improperly charged system or your climate control door that opens and closes for hot or air is not working properly and only stays on heat.

I have a 2002 pt cruiser that is blowing the ac 10amp fuse repeatedly. I mean within minutes of changing it. Also the ac is only blowing hot air. Can someone please help.


An AC system blowing hot air is usually due to a low freon charge or a non operational AC compressor. If the fuse blows, disconnect the compressor electrical plug and turn on the AC. If the fuse doesn't blow, suspect a compressor problem. If the fuse continues to blow with the compressor disconnected, there is a direct short between the ON/OFF switch and the compressor which can take hours to diagnose

Kia sedona compressor clutch does not turn?


check for fuse and relay problems in the ac circuit. disconnect the wire near the ac clutch and use a test light to see if there is power there. Remember that there are 3 units that will stop the clutch from working. Low pressure switch, high pressure switch and the thermostat. Best take it to an accredited ac specialist shop for a test of the system as you may have a leak and all the gas is gone.

the ac system needs air through the condenser ( radiator bit in front of the radiator) to operate correctly. IT it has no air then the compressed gas is to hot and will not turn to liquid and so the high pressure switch turns of the ac compressor. No problem when you are moving as road speed provides the air flow. Get an electric fan and have it installed before the condenser and connect it to the ac compressor circuit so that it is running all the time you have the ac compressor running. not the local mechanic.When dealing with ac systems the best people to take it to is an accredited ac specialist shop

Why is it that when i turn on my ac my car idol drops low and the car turns off


If you gassed the ac system your self then it mat be overfull and that is why it is not working and if you did no check for leaks (why else would need gas) then it may be all pumped out . The AC compressor takes a lot of power to drive and all cars loose around 300rpm's when it cuts in so if you have an idle too low then it will drop below needed idle rpm's . Most cars have a compensating unit the raises the idle rpm when the ac is working so check out your system for a faulty unit there.

Aircon air problems


put a tester at the wire to the ac clutch(bit behind the pulley) and turn on the ac and the blower motor. If it lights up then the problem is in the AC system. There are to pressure switches in the system that protect the compressor. On stops the compressor if the pressure on the outlet side gets too high and the other stops the compressor if there is not enough gas. Have an ac mechanic run a pressure test to see what the problem is . If the TX valve is blocked then the pressure will be high.

Could cluster fuse be prob why ac blowing hot? fan blows but hot air


Does the Compressor kick in when you turn on the AC? If it doesn't, the AC compressor is governed by the ECU. My AC went out along with an acceleration problem. hard starting, and unburnt fuel. I had my ECU rebuilt, and upon installation of the rebuilt unit, all worked perfectly again, including the AC.

I think the air compressor is bad in the truck


If your refrigerant level is OK and the truck blows cold air your compressor should be fine, in which case the noise is probably coming from the AC clutch which isn't too expensive or difficult to replace. If it doesn't blow cold air, switch the AC on and watch the compressor. If the clutch engages, but the compressor doesn't turn, the drive belt will squeal loudly and probably start to smoke. In that case it is the compressor which is expensive to replace. Most vehicles have an AC bypass that will temporarily cut out the compressor clutch under heavy load. If you are going uphill with the AC on or accelerating heavily you might notice warm air coming out of the vents for a short period until you let off the gas.

Please help me with my air conditioning for my 1995 jetta


HI, giving the compressor 12v directly is not the way to go as you are bypassing the entire fail safe cercuit. it seem to me that your ac gas is low(can be checked via ac pressure gauges) wich means you have a system leak sumwhere. as soon as your hi/low pressure switch(depending on system) detect inferior pressure to the spesified pressure ,the ac compressor voltage is cut in order to protect the pump from seizure.

Or perhaps your evaporator(small radiator like unit behind dash) can get freezed up caused by either too mutch system gas(check pressure) or poor opperation of the expantion valve. the evaporator then has a sensor(themometer) wich measures evap. temp and if the value drops below spec (usially round about7degrees) the ac compressor will be cut once again(fail safe)

Maybe your ac compressor overheats due to inferior system oil/oil capasity, also note that only some systems incorperate the function of measuring ac pump temp. then again temp to high= fail safe=no12v to ac pump.

Good luck.
