Chime/Thermistor

Vehicles equipped with a power liftgate utilize a chime/thermistor assembly. The chime/thermistor assembly is a small cylindrical shaped electrical component mounted in the rear license plate lamp housing assembly. The chime portion of the component produces the audible chime sound heard at the rear of the vehicle at the start of a power cycle. The thermistor is a temperature sensor used by the power liftgate control module to enable proper liftgate operation in extreme climate conditions.

The chime/thermistor cannot be adjusted or repaired and if damaged it must be replaced. Consult your Mopart parts catalog for a specific part number.

The chime function is activated by a hardwired connection to the power liftgate module. The thermistor provides a outside temperature signal to the power liftgate control module. As the outside temperature increases the resistance reading decreases, as temperature decreases the resistance reading increases.
