i turn the air on full blast but i feel nothing
my air and heat just stopped blowing all of a sudden.. i only feel a little blow on 2000 Cadillac Seville STS
You need to have the automatic climate control system checked, if you feel a "little blow" or low speed on your blower motor then the blower motor is probably ok. If you cant hear the blower motor spinning even at low speed then the motor may have failed.
possible fault with climate control or blower motor resistor is failing
