A/c compressor won't kick on

The a/c already wasn't cooling as well as before and then last night it stopped cooling completely. This morning I tried to charge the system but the compressor would not come on so I could not charge it. All fans will still come on and found no blown fuses. What is the next step? Pressure switch?

Take it to your local aircon mechanic to test the pressures he may recharge it with dye in the gas and then you'll need to take it back for inspection with a special light that shows leakage

The system likely has a leak, the compressor will not engage below a certain charge.

SOURCE: Radiator fan turns on randomly kills battery NEED HELP!

Check the relay inside the engine compartment. It may be sticking allowing the 12v's to stay on the cooling fan. Sometime this box that contain the relays are on the passanger side.

SOURCE: I had a 2004 honda cr-v in for an A.C. problem.

If everything checks out as you say then a likely culprit is either the dashboard ac switch or the fan switch (both must be on for the compressor to run). Check continuity on those switches or see if a wire is loose.

SOURCE: 1996 Honda Odyssey engine cooling fan stays on.

I don't thing there is a short there is radiator fan switch that control these fan, it works off of heat. There is also a fan relay that control look in fuse box inside the hood for fan relay and make sure its NOT stuck , if it isn't then its the fan switch.This switch may be bad and cause the fan to turn on. Replace radiator fan switch located on water outlet on engine and this should solve your problem. A

SOURCE: Air conditioner stopped cooling. Dealer diagnosed

It could be that there was more than one leak and the dealer found only one. The AC system has two pressure switches to protect the compressor from damage---a low press. switch cuts off the compressor when there is not enough refrigerant in the system, the high switch cuts off when pressures get so high they could blow out the seals. Both are a result of a leak--refrigerant leaks out and air can leak in. Air will compress and when it does, it gets hot--so no cooling, and pressures go way up. So the compressor may have been stopped by those protective switches.

Of course, there could be a bad relay or other circuit malfunction.

Another possibility is that the compressor sat too long before being repaired (but we are talking about weeks going by here, not days). The air and moisture (humidity) that leaks into the system during this time creates acids that will attack the metal reed valves in the compressor. On restart, the damaged metal valves eat themselves in short order. If this is the case, the compressor ran until it seized and will need to be replaced. This particular problem is impossible to diagnose. So the dealer may have done his best.

Testimonial: "Thanks. I did wait a few weeks before bringing car in for AC repair, so you could be right about the compressor. Ewwww."

SOURCE: I am preparing to recharge

the whine can be a couple of different things. one, it may be low on refrigerant oil, which will cause it to be drier than it should be, which, would of course, cause a whine. if the whine is heard even when the ac is off, then it could be that u got water in your belts, your belt might be loose, or some sort of belt issue. well to charge it, im pretty sure you know the procedure, but here it goes any ways: wear eye protection of course, and preferably gloves too, remove the cap off the lower pressure side, turn your ac on to max, connect your ac recharging house to your r134a oil first, then connect other end to the ac port. once you connect it, make a hole with the knob on the top of the oil container, release, and shake, until the bottle becomes cold, then empty. repeat steps with refrigerant, then stop leak if necessary. note: when done, turn away when removing the hose off the ac port as you never know if something can spray out.

i posted this link because this bottle has the hose which i stated attached to it, i know auto parts stores should sell it, if not, you can always buy it with a can like this one. another thing, i dont know if they still have it or even if its available in all areas, but i recharged my a/c not too long ago and i bought my bottles at walmart. i got 2 for around 24, and if you return the empty bottles with the receipt within a couple of days, they give you a core return of 10 dollars per can, so i recharged my ac for like 5 bucks, so you might want to check it out. no guarantess though. i think on the back of the bottle it says something about 10 dollars. hope this helps, and if you need any more help, let me know. goodluck.

Cooling fan won't come on when I turn on the AC


Your bigger problem is the compressor not kicking in. The cooling fan is not coming on because there is not enough high side pressure to turn the fan on. I would start by checking power to the compressor, fuses and relays would be inspect. Check to make sure there is the proper charge of refridegerant in the system.

My 2001 sunfire starts fine.but after i drive for about half hour it will stall and wnt start again for half hour.the oil light stays on when this happens.wassup with this?


This happened with my Sunfire. It was the radiator. The engine wasn't cooling, but the sensor wasn't showing that it was overheating. So the engine would start when it was cool, but as soon as it got hot, then if I stopped it wouldn't start again.

A/C Compressor won't turn on Can jump compressor from battery and compressor comes on & cools. Hi pressure switch checks out ok and 12 volts going to hi pressure switch no voltage to compressor


the high pressure switch kicks the compressor off when the pressure rises, the low pressure switch kicks it on, check that switch, unplug the wire and use a continuity meter to see if the switch functions, also check for power getting to the plug itself

hand it over to a mechanic or Nissan. If you recently had an M.O.T and it went of quickly then ask for a refund, even better, ask him to take a look at the car again

98 accord ac not blowing at all


This is very vague. Is the blower motor working (can you hear blowing inside?), is it blowing but it's hot? Can you hear the compressor running (open your hood and listen if something is kicking on and off). AC is so complex. It could be as simple as a freon leak or as complex as a compressor, hose, accumulator etc.
