GDUKOP 55111389AF HVAC Humidity Sensor — OE Replacement for Jeep Grand Cherokee, Dodge Ram, Chrysler Vehicles (2011-2023)

Overview

The GDUKOP 55111389AF HVAC humidity sensor is a direct OE-style replacement designed to bring balance back to your vehicle’s cabin climate. It’s compatible with a broad range of models across Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo, spanning 2011–2023 model years. The sensor replaces multiple OEM part numbers, including 926-369 and 55111389AD, to support a seamless restoration of humidity sensing in the HVAC system without guesswork.

Engineered for a precise fit, this sensor slots into the same housing and electrical connections as the original unit, helping to maintain consistent humidity readings that influence how the HVAC system modulates airflow, moisture control, and defrost behavior. While results can vary by vehicle and condition, many drivers notice the potential for a more stable cabin environment once the sensor is refreshed with a like-for-like replacement.

Why replace your humidity sensor

If you’ve observed erratic A/C performance, uneven cooling, or defrosting that isn’t delivering as expected, a malfunctioning humidity sensor could be a contributing factor. Fault codes related to the HVAC humidity system may also appear in some vehicles. Replacing with a compatible sensor offers a practical, non-invasive way to address these symptoms and support the HVAC system’s ability to respond to ambient and cabin conditions.
