Jaguar F Type Heating Failure: Flap Control Issue Alert

As someone with moderate experience working on Jaguars, I encountered a similar issue with my 2017 F Pace. The symptoms were nearly identical, weak heating performance and dashboard panel warnings related to the air distribution system. The root cause turned out to be a faulty wiring connection to the air distribution motor. The windshield fogging became a real safety concern before I got it fixed. After checking the blower motor, which was working fine, my mechanic traced it to corroded plug terminals that were causing intermittent connection issues. The repair involved cleaning the connection points and replacing a damaged wiring harness. Total cost was 95€ including labor. Since the fix, the temperature regulation and air distribution have worked flawlessly. What engine variant does your F Type have? This information would help determine if the issue matches the common pattern seen in certain powertrains. Also, do you notice any unusual sounds from behind the dashboard when switching between different air modes? Before taking it to a shop, try cycling through all air distribution settings several times, this can sometimes temporarily restore function if its just a stuck flap rather than an electrical issue.

Last service completed at 120000km and symptoms started appearing shortly after that milestone. The issue seems worse during cold starts, with noticeable heater core issues becoming apparent after about 5 minutes of driving. The ventilation system works normally for brief periods before failing again. Regarding your question about sounds, yes, there is a slight clicking noise from the dashboard panel area when switching between modes. The temperature regulation becomes completely unresponsive after this clicking sound occurs. Our air distribution settings are equally ineffective across all modes. Will try cycling through settings as suggested, but based on the wiring issue you described, it sounds like we might be dealing with a similar electrical problem. Was your repair covered under any extended warranty?

Thanks for the additional details. The clicking sound you describe matches exactly what I experienced with my F Pace before the repair. This typically indicates the actuator is attempting to move but failing due to electrical resistance in the circuit. The symptoms getting worse after cold starts and the timing after your service milestone are important clues. In my case, moisture had gotten into the connection housing during a routine service, accelerating the corrosion of the terminals controlling the climate control system. My repair wasnt covered under warranty since the vehicle was over 5 years old. However, the fix was relatively straightforward once properly diagnosed. The clicking from the dashboard panel area is the air distribution motor trying but failing to fully engage, exactly as in my case. One quick test: check if the clicking sound changes pitch or frequency when you adjust the temperature settings. In my situation, the sound became notably louder just before complete failure of the temperature regulation system. While cycling through settings might provide temporary relief, based on the similarities to my experience, you likely need the wiring connection checked and possibly replaced. The ventilation system behavior you describe strongly suggests an electrical rather than mechanical issue.

Thanks for sharing those details about your F Pace repair. The clicking sounds in my F Type are indeed changing pitch when adjusting settings, getting noticeably louder when switching between hot and cold temperatures in the climate control system. The HVAC unit symptoms match what you experienced, especially regarding the timing after service. My air circulation problems also seem worse after rain or high humidity, which supports your theory about moisture affecting the connections. I contacted the dealership about warranty coverage since my car is just over 4 years old. Unfortunately, the ventilation system components are only covered for 3 years unless theres documented evidence of a manufacturing defect. Given the relatively reasonable repair cost you mentioned (95€), I will probably proceed with the fix at my regular mechanic. Before booking the repair, I tried cycling through all the temperature settings multiple times as suggested. While this temporarily improved the windshield fogging issue, the heating problems returned within an hour. Based on all the similarities with your case, I will have them check the wiring connections first rather than replacing more expensive components.
