Hi,
according to the manual the ac runs when you set the airflow on defrost. Does it also run when you have the mixed defrost/floor on?? I can't tell on my 06 that the engine rpms change at all when I turn it to defrost. Does anybody know??
Thanks

 

If the defrost is on, your AC compressor will run. It helps remove humidity from the air which helps defog/defrost the windows.

 

^^^Exactly!

 

^^^Yep!
