If the air conditioner compressor in a 2002 Mercury Sable doesn't click on despite being fully charged with freon, it could be due to a faulty compressor, a malfunctioning relay, or an issue with the electrical system, such as a blown fuse. Additionally, the system may have a pressure switch that prevents the compressor from engaging if there's a problem with the refrigerant pressure, even if it appears charged. It's also possible that the AC clutch is worn out or there could be an issue with the vehicle's climate control system. A thorough diagnostic check is recommended to pinpoint the exact cause.
air conditorner doesnt blow cold air has freeon compressor doesnt kick on
If compressor is running 80-100% of time without recycling, it may still be low on freon. If freon pressure is good, may be expansion valve.
This is not a DIY job. It is illegal to release refrigerant into the atmosphere. Special equipment must be used to purge the system before removing and re-installing the compressor. The new compressor and system must then be charged correctly with refrigerant and oil. Take it to a professional.
shouldn't run anything else, my 94 doesnt.
if it doesnt come on it may be the air charged temp sending sensor.... if it doesnt come on it may be the air charged temp sending sensor....
it breaks. like mine has been for the past three years. therefore, the a/c doesnt work and it needs to be replaced. i love it. the transmission also enjoys to die.
Typical causes of a compressor not running are: low coolant, blown fuse in compressor circuit, bad compressor, bad temperature sensor.
No it doesnt and wont vibrate when it is being charged.

you would need to add freon
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
Mercury does not have enough atmosphere and is too hot / cold to support life.
