BUICK TERRAZA COOLANT PROBLEM

2006 Buick Terraza • 95,000 miles

The heat in my wifes Terraza cxl started to blow warm, it's not blowing hot air. I checked the coolant, it is good. I checked the fuses and everything is good there also. It blows warm air, just not hot air. Any suggestions would be helpful, thank you

Can check coolant temp to see if in operating range 190-210 Auto system is you set on a temp and HVAC adjusts either hot or cold manual you switch or slide lever to hot or cold
