    The wire i checked for power was on the wire harness side of the main power lead B4 the compressor. So the lack of power was well B4 the thermal coupler. And what if I used a jumper wire going straight from the battery to the compressor and by pass everything just to get the freon in the system. Also when I pulled the plug for the pressure switch I put a test light to the harness side of the plug (with the A/C switch on. engine off) and the radiator fan went on. This is the A/C actuated fan,since the new parts that fan hasn't gone on

Have you checked the thermal protector switch on the compressor? If you probe the wire with a test light and the compressor comes on replace the switch.

    You can just remove the relay and jump the two big terminals the compressor should come on. I still say probe the thermal protection switch though. It's a very common issue.

    There wouldn't be power ther untill the computer sees that the thermal switch is good.

Sounds like an ignition component failure check for proper resistance through primary and secondary ignition coil windings, refer to service repair manual for exact specs, also the ignitor magnetic pick up may be not up to snuff, the only other ignition component to replace or check is the ignition module and/or plug wires themselves, sometimes when extreme demand is put on the ignition system the plug wires must be high quality and completely isolated from one another. Spark plug wires when routing cannot come in contact with one another in the slightest proximity.

Have a 1988 Lincoln Town Car, have put in new A/C compressor,new drier, new condenser, new hoses, new evaporator & full of freon. But compressor want cycle, what could be my problem???


If the compressor wOnt cycle, it means that the pressure is not correct. How much freon, (and what type) did you put in, and did you PULL DOWN (with vacuum) the system to about -29 inches before putting the freon in? Did you use manifold gauges? If so, what is the high pressure, and what is the low pressure, at what ambient temperature?

It sounds like you've done just about everything except to check if there is a bad or intermittent wire causing this or perhaps your low-pressure safety cutout switch is possible going bad causing the compressor to kick on and off?

1994 Toyota Previa compressor not working


You may need to try to find a used shop manual for this repair.
The DIY books don't show wiring diagrams for the a/c system.

Is the pressure detection switch engaged? It detects pressure in the cooling system. This switch shuts down the clutch to prevent the compressor to run when there's a leak.

Sometimes there's a looking glass on the expansion bottle showing tiny bubles. A large blob of air indicates too much air in the system. Pressure might not be enough to engage the switch when there's too much air left.

Just replaced a/c compressor and related underhood system components, vacuumed system to 29"hg and holding. Can't get compressor to kick in. Have bypassed low pressure cutoff switch. Trying to charge...


If you have the system down to 29" you shouldn't need the compressor running. You don't indicate if your trying to recharge with 12oz cans or with a 30# bottle. With the cans you should be able to turn them upside down and put the freon in as a liquid. It should just get sucked into the system. When no more will go in by that method there should be enough in the system to allow the compressor to engage when you turn it on. Then you can top the system off by adding the rest as a gas (can upright). I'm assuming you're connected to the low pressure port if you're using cans. We use a machine that pumps the freon into the system so the compressor doesn't get used in the process.
