Heater is blowing cold air even though temperature gage says 210 degrees

If the mechanism that controls the blend of air temperatures desired is not working properly, cold air can blow even though warm air is selected. So, diagnostic testing needs to be performed in that system. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
