The Mazda Rx-8 is having an issue that is coming up more frequently now from a faulty A/C switch or heating system failure. The heat does not come into the vehicle when the heat is turned on and only cold air comes into vehicle. The failure happens in the beginning only randomly until the unit completely fails. The A/C modular is a electronic switch that changes vents and A/C or heat. The vent mechanism still functions but the heat is never transferred into the vehicle. The consequences from this item failing, especially in the winter time, the windshield cannot be defrosted and driving down the road way human exhaustion will cause the window fog up impairing driver's vision. As well as cold temperatures within the vehicle that do not suffice while driving in cold weather.
