I will look in the service manual tonight when I get home. It will have to be something that would be common with both. Could be a vent door that is controlled automatically could be jammed. I would think that even if the blower motor did not work you would still feel a little cold air or heat.

there is temp air duct with a door that will let in outside air , ac , heat. it is controlled by vacuum. it is in the dash, or under the dash.
