VW Bora Cabin Fan Dies, Control Module Fix Guide

The blower motor failure you describe matches what happened on my 2006 VW Golf with the 2.0 FSI engine. The climate control system stopped working completely, which made driving quite uncomfortable. The HVAC system diagnosis revealed two common issues: a failed blower motor resistor and the actual blower motor itself. In my case, the motor had seized due to worn bearings, causing the resistor to burn out as well. This is a known weak point in these VW models. The repair involved replacing both components since the resistor usually fails when the motor draws excessive current before completely stopping. The air flow problems started gradually, first losing certain fan speeds, then total failure. This was a significant repair that required partial dashboard disassembly to access the blower motor assembly behind the glove box. A certified shop needed about 3-4 hours to complete the work. The check engine light in your case could be triggered by the electrical system detecting the abnormal current draw from the failing blower motor, which is similar to what happened with my Golf. Given your symptoms and the age of your Bora, you likely need both the blower motor and resistor replaced to restore proper air conditioning and heating function. This is not a repair you want to postpone, as proper cabin ventilation is essential for both comfort and safety.

Thanks for sharing your Golf experience. Good to hear I am not alone with this HVAC system problem. My Bora is still sitting in the garage and I am gathering info before taking it to a shop. How much did you end up paying for the complete repair of the blower motor and resistor? Also wondering if you have had any air circulation issues since the fix was done? The heater fan in my car is completely dead now and I want to make sure I budget enough to get it fixed properly the first time.

Had the repair done last week and can confirm it solved the fresh air blower issue completely. The cabin fan is now working perfectly across all speed settings, and the check engine light went off after the fix. The total cost came to 365€, which included replacing the faulty blower motor and labor for accessing the HVAC system components. The electrical wiring also needed some attention where it connected to the motor, but this was included in the service. Since the repair, the heater fan has been performing flawlessly. No more issues with air circulation or ventilation. The shop confirmed that the original blower motor had failed due to bearing wear, which is exactly what they expected to find in these models. The investment was worth it for proper cabin climate control. Would definitely recommend getting it fixed soon, as driving without a functioning cabin fan can be quite uncomfortable and lead to windshield fogging issues in certain weather conditions.

Thanks for the tips, everyone. Finally got my Bora fixed yesterday after finding a reputable VW specialist. The blower motor replacement turned out exactly as predicted, both the motor and resistor needed changing. Total cost came to 410€, slightly more than expected because they found some corroded wiring that needed attention near the HVAC system connection points. The repair took about 4 hours, with most time spent accessing the components behind the dashboard. The air circulation is now perfect and the heater fan works on all settings. Such a relief to have proper cabin ventilation again. The check engine light cleared up right after the repair, confirming the blower motor was the root cause. Definitely worth every cent to have it done properly. No more foggy windows or stuffy cabin issues. Really appreciate the advice about replacing both parts, saved me from potentially having to do the job twice.
