what is a heat regulater and were is it
my defrost comes on by itself and my heat and air woint work
The heater control valve or heater regulator is located under the instrument panel, just next to the heater core. There are a few things that can cause this problem. Reason #1 a low coolant level can cause the heater core to receive less coolant flow hence causing the heat to come less quickly. Reason #2 sticky heater control valve, if this control valve is stuck closed coolant can't enter the heater core hense wont heat up the cabin. Reason #3 clogged heater core, over time some heater cores will clog up even sometimes start to leak in cabin. All these are normal circumstances and should be checked.
