So I decided to do a little more digging. I opened the thermostat which looked fine. Nothing is burnt inside. I disconnected the white furnace wire and tried the air. Everything works fine. At this point I am guessing that it is the thermostat that maybe went bad. Picked up a new one on my way into work ($50) and will wire it up tonight. I can return it if this doesn't fix it because it is an electrical part but it is worth the gamble to me because I can replace it myself versus the shop labor rate of $75 per hour. I will let everyone know how it goes.
