Hi guys

just a quick question

is it normal that when i turn the position of air distribution knob to windshield/defroster the AC compressor automatically turns on (and makes the typical compressor noise), but the AC light remains off ?

Is this normal in new cars now ?

as far as I remember my previous cars did not have this feature ?


Thanks

jj

yes, it's normal. Dehumidified the air and let the defroster works better and quicker.

Every car I've had has done the same thing.
Just use as needed or your gas mileage will be affected.

Does anyone know if the ECU will regulate the compressor and turn it off when not needed?

In my 2003 Sentra, it had an "undocumented feature" that once the compressor is turned on, it will not shut off until you turn the engine off!!! :mad:
