SOURCE: Volkswagen passat 96 AC relay location

You should never connect a 12volt to the compressor solenoid.unless you unplug it first, because on some cars the ac solenoid is driven by an electronic circuit. Semiconductors are very sensitive to excessive current. I once had to repair the computer on a mercedes because the other mechanic did that. Luckily I know how to repair electronic circuits, or they would have bought a 500 dollars computer the little chip that blew only costed a dollar fifty cents at radio shack,.LOL. Anyways back to your problem, Have you checked if there is a leak, and all the refrigerant might have leaked out? This would prevent the compressor from coming on. Along the ac line there is a switch, sometimes by the reciever drier, when the system looses refrigerant the pressure inside drops and that pressure switch disable the compressor. , and the compressor wont come on. This is to protect the compressor, because it will be damaged if you run it without refrigerant. Ac clutch solenoid is usually is not driven by relay, because an ac solenoid don't really take much current to to kick in, unless of course it is shorted. It would either be directly from the inside switch usually in series with the fan control or driven by a small transistor in a circuit, and the electronic circuit is driven by the ac controls inside. I think the problem with your ac is that it has no refrigerant thats why the compressor wont come on.

SOURCE: how to replace front lambda sensor

The oxygen sensor, (also called the lambda sensor), is right after the exhaust manifold, which is on the back side of the engine, so you need to reach it from underneath.
However, it is expensive, so you may want to take it out carefully and simply have it checked first.
With an ohmmeter you can tell if it is burned out.
0 or infinite ohms is bad.
I believe it should be around 1500 ohms, but don't remember exactly.
The other thing is deposits like carbon can make it ineffective, and can be cleaned sometimes.

If you put a new one in, a little antizsieze is a good idea, but don't put on much, because you don't want to contaminate the sensor. Just enough to make removal easier. Remove and clean it every year.

Compressor keeps kicking off 1999 Buick Century AC


Your ac system is most likely low on freon, or the cooling fan is not working.
When you turn on the ac the cooling fan should stay on.
If it stays on then you are low on freon.

firstly i think you have overcharged the Ac system as the most it should hold is 650 grms for this system on this model ,if too much gas it will click in and out and slow the engine down ,as for the gauge readings then renew the sensor its on the housing at the front in the plastic housing ,depending on year and model this is where most are ,but some later models have a sensor at the back of the head left side from front

You say temp fan?If you mean the cooling fans,then the ac is out of freon most likely,the freon has to be in the system,and enough to kick the compressor on,therefore turning the cooling fan on.

A/c issue


Could be a couple things - one, if the fan switch for the AC condenser is not working, it'll keep the AC from kicking on, but that's usually seen by the compressor not coming on. When you activate the AC, do your RPM drop down at all? It should. If it does, the compressor is kicking on and you probably have a problem with the expansion valve, which is what flash chills the air. The car is pumping freon around but it's not cooling enough to cool the car. That's likely an expansion valve problem.

If you turn it on and the revs don't dip down momentarily, the compressor isn't coming on, and it could be the fan switch underhood or the AC relay.
