Heater was working fine. Came out from shopping and heater was not blowing hot air. AC works fine. The position selector runs through all positions without a problem. I have check fluid level it was a little low so I topped it off bleed the air out of the system as best I could. I noticed this morning that there was still a little air sputtering but not a lot mainly fluid. Any suggestions on what I need to do
