You could have a restricted heater core, a stuck open thermostat, be low on coolant, or have a bad blend door motor or actuator. Does it blow heat at highway speed?Can you feel the air blowing?If you turn the control from hot to cold can you feel a temperature change in the air coming out. With the car sitting still fully warmed up try reving the car up in short quick burst, like vroom wait vroom wait for about 3 or 4 minutes and see if the air gets warm.

It only blows cold when we are sitting at a stop light. When I give it gas it blows heat. I have also heard air in the line that it needs burped.

Yeah, I would suggest that you do a heater core flush and then a good bleeding of the system. The fact that the air is hot at higher rpm's is a very good indicater that there is a restriction in the heater core. Flush in in both direction and until it looks like pure water.
