The GDUKOP 55111389AF is designed to match the original equipment fit and connector layout, making installation straightforward for many 2011–2023 models. It swaps in for several factory part numbers, so it’s a practical spare when troubleshooting HVAC issues or performing routine repairs.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles will accept this humidity sensor?\u003c\/h3\u003e\n\u003cp\u003eThe sensor covers a wide range of Chrysler, Dodge, Jeep, Ram, Fiat and Alfa Romeo vehicles across multiple model years.

A degraded sensor can cause the HVAC controller to misjudge cabin moisture, leading to inconsistent cooling, extended fogging, or stored fault codes. Replacing the sensor returns correct humidity input so the control algorithms behave as intended.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eResolves erratic A\/C on\/off cycling by providing stable humidity data\u003c\/li\u003e\n  \u003cli\u003eImproves windshield defogging behavior through correct moisture detection\u003c\/li\u003e\n  \u003cli\u003eHelps clear or prevent P1009-related fault codes when replaced\u003c\/li\u003e\n  \u003cli\u003eDirectly replaces multiple OEM part numbers for compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill installation be difficult and what should I check before buying?\u003c\/h3\u003e\n\u003cp\u003eInstallation complexity varies by model and how the HVAC assembly is accessed. Many owners or technicians can replace the sensor without major dashboard disassembly, but some vehicles require partial dash removal.
