Rear AC Failure Hits Grand Voyager Climate Controls

Had the same issue on a 2009 Chrysler Town & Country Diesel. The air distribution system failed due to faulty actuator motors controlling the rear HVAC flaps. System diagnostics revealed multiple error codes related to the air circulation controls. The repair involved accessing the rear HVAC unit behind the panels to check cable connections and electronic components. Main problem was a damaged wiring harness and corroded plug connections affecting the automatic climate control signals. This was a serious issue requiring complete removal of interior panels for proper HVAC repair. The faulty components prevented proper air distribution and caused the entire rear climate system to stop working. Repair required: Testing all actuator motors, Replacing damaged wiring harness, Cleaning corroded plug connections, Recalibrating automatic climate control system, Full system diagnostics after repair After fixing the connections and replacing damaged components, the rear air conditioning worked perfectly again. While complex, this is a known issue that competent shops can resolve.

Thanks for sharing your experience. I had a similar problem with my 2006 GrandVoyager where the flap actuator failed completely, leaving rear passengers without any climate control. The mechanic replaced the air distribution module and rewired some connections. Can you remember roughly how much the repair cost in your case? Also wondering if youve had any other HVAC issues since the fix? My automatic climate system has been working fine for 6 months now, but Id like to know what to watch out for.

Good news to share, after dealing with those frustrating rear ventilation issues, the repair was actually quite straightforward and cost-effective. The mechanic spotted a faulty cable connection affecting the air distribution system. Getting this fixed only came to 95€, which was a relief compared to what I initially feared. Since the repair, the automatic climate control has worked flawlessly. The system diagnostics show no more error codes, and the rear HVAC performance is back to normal. The car cooling works perfectly throughout, with proper air distribution to all areas. Looking back, the issue was less severe than expected, just a damaged connection rather than a complete actuator failure. If your repair has been holding up for 6 months without issues, that is a good sign. These climate control systems are generally reliable once properly fixed. Just keep an eye on any unusual sounds from the air distribution system or inconsistent cooling, these can be early warning signs. But with proper maintenance, the HVAC system should continue working reliably.

Thanks for the feedback. Finally got my rear HVAC repair done last week. The mechanic found the actuator motor had completely seized up, causing the air distribution problems. Total bill came to 380€ including parts and labor. The repair process took about 4 hours since they had to remove several interior panels to access the climate control components. They also discovered and fixed some corroded wiring while in there, which explained why the automatic settings were malfunctioning. Air conditioning is working perfectly now, rear passengers are finally getting proper cooling again. The automatic climate control responds correctly and system diagnostics show no more error codes. Will definitely keep monitoring for any air circulation issues, but the mechanic assured me these repairs typically last for years when done properly. Glad to have this fixed before summer hits.
