Jaguar I Pace Climate Systems Hit Multiple Failures

As a Jaguar I Pace 2019 owner with some experience in electric vehicle maintenance, I encountered nearly identical climate control issues last winter. The symptoms matched yours exactly, multiple climate-related functions failing simultaneously, suggesting a central system problem. The root cause turned out to be a faulty connection between the humidity sensor and the main climate control module. This automotive sensor serves as a central component for various climate-related functions. The repair involved checking the wiring harness and replacing a corroded plug connector that was affecting visibility systems and climate control functions. The total repair cost was 95€, mainly covering diagnostic time and connector replacement. The fix was relatively straightforward once the workshop identified the specific connection issue. To better assist with your situation, could you share: Whether you notice any pattern when these malfunctions occur (cold starts, after rain, etc)? Are there any warning lights on the dashboard? Have you recently had any work done on the climate control system? Does the issue persist after a complete vehicle restart? These details would help determine if youre dealing with the same connector problem or potentially a different sensor malfunction.

Thanks for the detailed info on the connector issue. My I Pace was serviced recently at 93167km and the technician did note moisture-related concerns in the front electronics. The malfunctions seem most noticeable during damp weather conditions. No warning lights appear, but the climate control system becomes completely unresponsive. Restarting the car temporarily resolves the issue for about 15-20 minutes before the problems return. After inspecting under the hood, I noticed slight corrosion near the main humidity sensor housing. This matches what you described about the car sensor connections being the root cause. Will have the workshop check the wiring harness and connector as you suggested. Would you recommend inspecting any other automotive sensors while they have it apart? I want to avoid multiple visits if other components typically fail together.

Glad you found my previous connector advice helpful. The symptoms you describe, especially the temporary fix after restart and issues during damp conditions, strongly match what I experienced. The corrosion you spotted near the humidity sensor housing is a telltale sign. Since youve already noticed moisture-related concerns in the front electronics, definitely have them check the entire wiring harness in that area. In my case, the electrical issue spread beyond the initial connection point, affecting multiple car sensor systems over time. While the technicians have the front assembly apart, request inspection of: The ambient temperature sensor connections, The climate control module ground points, The windshield-mounted rain sensor wiring, The dashboard warning system connections The total diagnostic and repair time should be around 2-3 hours. My final repair ended up slightly higher at 180€ because we replaced additional corroded connectors as preventive maintenance. This proved worthwhile as I havent had any visibility or climate control problems since. The temporary fix after restart indicates the connections arent completely failed yet, which is good timing to address it before more extensive damage occurs.

Thanks for the detailed inputs. I've scheduled the repair for next week and will have them check all those connection points you mentioned. The moisture correlation makes perfect sense given our recent weather and my observed symptoms. Based on the windshield fogging and climate control issues getting worse during damp conditions, I agree its likely the humidity sensor wiring causing these malfunctions. The quoted repair cost of 180€ seems reasonable considering the thorough inspection needed. Ill make sure they document any additional corrosion found since climate system problems seem common in the I Pace. Good to know that replacing all affected connectors provides a long-term fix rather than just addressing the obvious malfunction. Really helpful to learn this is a known issue with a clear repair path rather than some obscure electronic gremlin. Will update once the work is complete in case others run into similar climate control problems with their vehicles.
