Question about 1994 Volvo 850

1 Answer

A/c system is full, compressor cycles normally when below 90/95 outside, but when conditions are very hot (like when I need a/c) compressor cycles on/off every ten seconds, and does not remain on long enough to cool the car. Otherwise, a/c produces cold air fine.

Sounds like the a/c pump clutch is starting to wear out, when the gap becomes too large it will cycle on and off constantly. There is a simple fix someone came up with that I found on Volvospeed you can do to fix this problem. It only takes a few min and wont cost you more than a couple dollars, I did it myself and it worked great.

Why is my Air conditioning compressor cycling on and off?


Likely, you've lost your freon due to a leak. If the leak is slow, you can add a leak sealant and more freon yourself. If it's a major leak, that will work for a few days, and then all leak out.

AC NOT WORKING PROPERLY


You've got some of the picture, but not all of it.
You need to know what the high and low side readings are, so yes you do need the gauge set. If the system is charged, and the low side is not dropping below 25psi, I would guess the low side pressure switch is faulty. But if the low side is dropping below 20psi when the compressor stops, the system may be low on freon. Which means you have a leak somewhere.
The hissing noise is freon flowing thru the system which could also indicate a low charge.

GMC Acadia AC not working properly


Not sure if I'm too late to answer this one, but you're describing a low refrigerant condition. The hissing noise and constant cycling of the compressor clutch are indicators of that. You should recover the system, record how much refrigerant was recovered, evacuate the system (with a vacuum pump), add A/C dye, and recharge the system to capacity. Common leak areas on these vehicles include the A/C condenser (located in front of the radiator), and the evaporator (located inside the dash, and requires complete removal of the interior dash to replace it). If you can't find a visible leak after running the recharged system with dye for several weeks and it starts to blow warm again, you will need to use an R-134a leak detector to "sniff" areas of the system for a refrigerant leak.

Compressor turns, holds a charge but does not blow cold air even when I turn on the outside air it blows warm air


OK, this is air-conditioning 1-0-1

You say that i holds a charge, and the compressore turns, but does the comprressor cycle on and off, as this is indicating that there is enough charge, and once there is low pressure detected, it turns the compressor on, and when it reaches a high pressure, the compressor cycles off.

Lastly, when engine running and AC on, if you feel the 2 pipes going in to the firewall, one should be hot, the other should be cold ???...is this happening ???

My compressor cycles and purges in hot weather. After a while of these cycles, it overheats and shuts down completely. Then only hot air comes out & it smells like a swamp. after it cools down it wroks...


It looks like there is a technical service bulletin available you might want to check out. It is TSB No. AC002–04 it states In high ambient temperature areas, some 2004 – 2005 model year Scion xB owners may
feel that the A/C system does not blow cold enough air. This procedure provides a
method to improve this condition. Bring it in to a dealership and see what they say. I hope this helps you.

Compressor seems to cycle on and off 2005 nissan maxima


For protection of your compressor the system has a low pressure cut-out switch that turns the compressor off when pressure is too low (normally due to insufficient charge). This cycling on/off indicates low freon level. Charge the system and you'll be OK.

A/c


if you just added cans on freon to the system without gauges to see how much is in it,you have it over full, if the system is over full, it cant curulate .if it dont curulate it wont cool, i had one that was to full ,the hotter the outside temp got it stopped cooling, when it was 80 degrees it done fine when it hit 90 it stopped curulating,no cool.check it with gauges,check a/c fuse in compressor ,hope this is some help to you, thanks robert b.

Idle Revs With Front Defrost


when you use the front defrost in the winter the cycling of tha a/c compressor will cause this condition.

when you use defrost the a/c is run to de-humidfy the air that is blown onto your windshield.


in the summer this is not a big deal as it is hot enough outside to keep the a/c system pressure above the compressor clutch cycle threshold. but in the winter the general lack of heat in the ambient air and the lack of humidity results in rapid cycling of the ac compressor.

the idle is bumped up to compensate for the load of the a/c compressor, or else your engine would stall out. but when the compressor is disengaged the idle is dropped. but it raises again when the compressor cycles back on.

there may be a good chance that your ac is under charged after all these years. when the weather gets warmer have the charge level in your ac system checked.

a low charge will also increase the on off on off cycling of the ac compressor, usually resulting in the complaint that you have. so the base issue of your problem is low ac system charge.

1994 Hyundai Excel Air conditioning RADIATOR´S FAN works always very fast


this not really a problem as the fan speed is controlled by the high preasure switch in the ac system the hotter it is outside the higher the preassure will be in the system as hot as its been the preasure is high already when the compressor cycles it pulls suction on one side and outputs high preasure on the other the fans cool the condenser the higher the ambient temp the faster they go so all is fine...
