I am not a mechanic, and do not have access to one.  I am stuck in the Georgia dust until I can problem solve this.  Thanks everyone-lily

Low coolant light is triggered by the sensor in the coolant reservoir. As far as the heat or air not working, I suspect when the blend door was replaced something wasn't hooked up properly or a connection is being pinched.

I agree with the previous poster. Oftentimes before replacing the blend door(s) whom ever doing the job will connect the door and test before installing .. this habit will cause problems which you have described.
