| PERFORMANCE ORDER |  | 1. When the engine is cold (coolant temperature below 60 ?� C), connect the voltmeter between a wire supply to the heater (usually thick red wire) and "weight". If the voltmeter does not register the battery voltage, check the temperature switch and the heater relay. | | 2. Connect a voltmeter between ground wire heater (black wire) and "weight" of the car. The registered voltmeter should be very low (0.25 volts or less). If the voltage is higher, check the grounding of the heater. |  | 3.

If the recorded voltage is greater than 0.25 volts, then the temperature switch partially or completely open. Check it by disconnecting the wires and connect an ohmmeter between the terminals of the temperature switch. Meter should indicate an open circuit, if the switch is open, and therefore, the switch is faulty. If the ohmmeter indicates that the circuit is closed (indicating that the power switch), check the ground wire that connects the switch to the "weight" of the car. | | 3. Disconnect the ground wire in the supply must be rated voltage of the battery. If not, check the heater relay. | | 4.

If the recorded voltage lower check the temperature on the conductivity of the switch, as described above. The switch must trip when the engine is hot, if not, then it is defective. |
