why dont the heat come on i my 1998 intrepid .it has climate control.

From the question I'm not sure if you mean its not blowing at all, or its not heating up. If its not heating up, the first thing I would check is the coolant level. The thermostat could be sticking as well. If its not BLOWING.. you may have an issue with your blower motor or blower motor resistor. Any other details would help. good luck
