VW Transporter Blower Motor Failure Fix Guide

Had a similar issue with my 2010 VW Crafter Diesel last winter. The blower motor failed completely, making the climate control system unresponsive regardless of settings. After proper diagnosis, the problem turned out more complex than initially suspected. The electrical wiring behind the dashboard had melted near the blower motor resistor, causing both components to fail. This is actually a known issue with these vans when the original blower motor starts wearing out. The excessive current draw slowly damages the wiring before the motor finally stops. The repair required: Removing the entire dashboard, Replacing the blower motor assembly, Installing new electrical wiring harness, Replacing the resistor pack, Recalibrating the climate control module This was a serious repair requiring specialized diagnostic equipment and about 6 hours of labor. The air circulation is now perfect, but I recommend going to a shop that specializes in VW commercial vehicles. A general mechanic might miss the underlying wiring damage and only replace the motor, which could lead to the same failure within months.

Thanks for sharing your experience. Your repair sounds exactly like what I am experiencing with my Transporter. I am glad to hear you got it fully resolved, especially since these HVAC system issues can be really frustrating. Would you mind sharing how much the total repair cost you? Also curious if the heater fan and air flow have continued working properly since the fix or if you have had any other related problems pop up?

The total repair came to 365€, which covered replacing the faulty blower motor and all associated work. Since getting it fixed, the cabin fan has worked flawlessly for the last few months. The air conditioning and heating systems are functioning perfectly with proper air flow at all fan speeds. Unlike the previous troublesome repair experiences mentioned, this fix has proven completely reliable. The climate control responds instantly to adjustments, and the heater fan maintains consistent performance regardless of the weather conditions. For anyone facing similar issues, investing in a proper repair by a qualified shop is worth every cent. A failing blower motor often indicates other potential problems in the system that need addressing to prevent recurring issues. In my case, the thorough repair job eliminated all the air circulation problems I was experiencing.

Thanks for the advice. I took my Transporter to a different mechanic who specializes in VW vans. What a difference proper expertise makes! They found the exact same wiring damage behind the dashboard that you described. The fan speed controller and surrounding electrical wiring were completely shot. The full repair took about 7 hours but the climate control system now works perfectly. They replaced the entire blower assembly, rewired the damaged sections, and installed a new resistor pack. Total cost was 420€, more than I hoped but worth it for a proper fix. The air flow is finally back to normal and the cabin temperature stays comfortable. No more driving with the windows down just to get some air circulation! After my previous frustrating mechanic experience, I am relieved to have this sorted properly. The new shop even showed me the melted wiring they removed, which helped explain why a simple blower motor replacement wouldnt have fixed the underlying problem.
