Recently the car ran hot. The coolant air bleeder had a seal break. I have had that replaced. Every since then its been blowing cold air. The air will heat up when I get on the interstate, then cool back off once I get off. Today I also noticed that the coolant in my coolant reservoir was boiling. All the while the temperature gauge in the car remained normal, between 1/4 and 1/2.

Cold air in heater is normally from low coolant. When car cools down check your coolant level to make sure the jar is filled to correct level. Try that first and make sure your cap is tight.

Check your thermostat for proper operation and have it pressure checked for internal leaks as it could be a head gasket or intake gasket.
