A/C compressor engaging.........

[ArtistsRifles]

Question: Should the A/C compressor keep engaging every so often when the air distribution knob is on anything other than A/C or Max A/C??

Listening to ours running with the bonnet up whilst some friends oggled it we heard a loud click every minute or so and found the A/C compressor clutchwas engaging. Only way to stop it was to turn the air distribution knob to "Off"
I was under the impression the compressor clutch shouldn't engage unless either A/C or Max A/C were selected???

The compressor runs in every setting except off, and floor only, so thats normal.

This appears to be true for first gens only.

The reason for it being on in the other settings on the later models is that the A/C not only provides cold air it dehumidifies also; this may be desirable on the other settings. In addition it keeps the refrigerant oil circulating.

Thanks everyone - that puts our minds at rest!!! I was dreading the thought of going near a main Ford UK stealership with a problem on an Explorer's A/C system.
If they can't get a key right what chance have they got on an A/C system??
