Thanks for the responses. Swapped out the T-Stat last night, changed coolant.
No heat still, but after driving it more this morning, it most of had an air pocket, cause now she has heat!!

Thanks again.

 

I suspect it is one of the blend doors or controls. As I went ahead and replaced the thermostat, did a coolant flush. I had heat the next day, but I also have no control of it, its wide open hot, no changing the temp.

The only work done before all this happened was a windshield replacement. Makes me think they dropped something down in the vent.

Thanks for all the great responses, any other thoughts, ideas.
