I have a 2001 dodge ram, 5.9L, 2WD, auto trans with A/C basic control panel.
When I am driving with AC on normal to dash panel vents it is cold just fine.
When I put on my brakes, I hear a labored hum or change of sound in the dash and warm/hot air comes out of AC panel vents. After releasing brakes and driving a bit, it cools down back to normal cold.
I know the brakes and AC ducting system are all controlled by vacuum, so what is going on?
I have replaced all the dry-rotted vacuum lines and connectors in my vac system and it still does this.
Thank you to anyone who can point me in the right direction.
