Airconditioning compressor switching
I see my airconditioning compressor clutch being activated now and then when the airco is switched to off. My Jeep has the automatic airco system, but i keep normally both fan and airdirection selectors in manual. Is it normal behaviour that the compressor is switched on in this case:confused:

Hi Frank.
The A/C compressor is switching on and off vhen your "mode selector" is in the "window mode" or "window and feet mode". If you select the panel or panel and feet and you turn off the snowflake symbol then your jeep is running with the A/C off.hope the information is usefull.
Best regards

Hi Michael,

Isnīt it so that when the airco switch light is off, that the compressor should not run at all? Last week when i was using the heater ( with the system in manual mode), i still saw the compressor switching, but the airco was switched to off.
Doesnīt look normal to me.

hi frank.
I know i does not seem normal, but it is how chrysler and jeep vehicles are made, it's something with safety and they want dry air on the front windshield, to avoid a foggy vindow, at least that's what I've been told. The only way to by-pass it is to disconnect the connector at A/C compressor.
Best regards

Hi Michael,

Ok, i will try this out tonight, because iīm not sure in which position the mode switch was. But your story sounds ok. Just using the airco for removing the water out of the air to prevent misting of the windshield. :thumbsup:
I will check it out and let you know.
Thanks for the help.

Best regards x Frank.

Re: Airconditioning compressor switching
Michael is correct on that it is ok for your compressor to kick on and off with the deffrost feet and defrost. even with the ac button off it will still do this.

Re: Airconditioning compressor switching
Ok guys, thanks for the help. Checked it out and indeed the compressor only automatically kicks in when airflow is directed to the windshield or windshield/foot position and not in any of the other positions. Good to know its allright like this. :)
