Section 946 (Power Liftgate System): Chime/Thermistor: Description
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 portion of the component is a temperature sensor used by the power liftgate control module.
The chime/thermistor cannot be adjusted or repaired and if damaged it must be replaced. Consult your Mopar™ parts catalog for a specific part number.
