Ok. Just had the auto shop pull and refill my compressor a few weeks ago. I had done some work under the car around the compressor and the car was blowing warm, so I wanted them to check for leaks in the process. No leaks at the compressor. It blew cold.
Now it's blowing warm, barely above the outside temp.
I have checked my vacuum lines, the heater control valve, barn doors are closing. Everything looks good.
I also went to check the infamous heater clips that break. They are connected well, but they don't move. Does that mean they are stuck in heat mode?

What do I check to see why the arms aren't moving?

Thanks!
