Amarok Climate Control Failure: Fix Guide & Costs

Having had a similar issue with a 2018 VW Tiguan, I can share some experience from dealing with electronic faults in the climate control system. In my case, the symptoms matched yours almost exactly, unresponsive controls and complete AC failure. After a thorough diagnosis, the workshop found damaged electrical connectors in the wiring harness leading to the climate control module. The constant heat and vibration had caused the connections to deteriorate over time. The fix involved replacing several corroded connectors and repairing a section of the wiring harness. Total repair cost was 95€, which included diagnostic time and parts. The whole job took about 2 hours, and the air conditioning has worked flawlessly since then. However, to give more specific advice for your case, could you share: Have you noticed any warning lights on the dashboard? Does the blower motor make any noise when you try to activate it? Are there specific error codes you can share from the diagnostic scan? Did these issues start suddenly or develop gradually? These electrical issues can have multiple causes, and getting these details would help narrow down whether your problem is similar to what I experienced or if it might be something else entirely.

Had mine checked during the last service at 91791km. The workshop found that the blower motor had failed completely and the temperature sensor was showing incorrect readings. They initially suspected a faulty control panel, but diagnostic tests revealed the actual culprits. The air conditioning was also affected due to a damaged wiring harness that connects to the climate control module. Total repair costs came to 580€ including parts and labor. The system now works perfectly. Worth noting that error codes P0532 and P0533 appeared during diagnosis. These should match what you are seeing in your scan.

Based on your service experience, it definitely sounds like we had very similar issues with our VWs. While my repair costs were lower since I only needed wiring harness work, the combination of a failed blower motor and temperature sensor explains your higher repair bill. Those error codes you mentioned (P0532 and P0533) are classic indicators of HVAC system pressure sensor problems, which often occur alongside wiring harness damage. The power supply issues to these components can trigger multiple electronic faults in the climate control system. Good to hear your repair was successful. After my initial wiring fix, I actually started having temperature sensor issues about 6 months later, but caught it early before the blower motor was affected. Regular system checks have helped prevent any major air conditioning failures since then. For anyone else reading with similar symptoms, checking the wiring harness connections should be the first diagnostic step, as it is often the root cause of these electronic control issues.

Thanks for sharing those details about your repair experience. You are right, these P0532 and P0533 codes match exactly what I am seeing. It is helpful to know what parts needed replacement in your case. I will have the workshop focus on checking the blower motor and temperature sensor first, along with inspecting all electrical connectors in that area. A failed power supply to the HVAC system components seems like a common issue with these models. The 580€ repair cost gives me a good reference point for what to expect. While not cheap, having a properly working air conditioning system is worth the investment. Will schedule an appointment to have mine diagnosed properly. Thanks again for confirming that these electronic faults can be resolved with the right diagnosis and parts replacement. At least I know now what to tell the mechanic to look for when checking the climate control system.
