VW T6 Transporter 2017 heater motor replacement.

[Snowy1957]

I’ve just got back from my local VW dealer, the heater blower resistor has been replaced twice under warranty & has gone again after only a month.
This time they’ve diagnosed the heater motor as being the problem, sadly the cost for a replacement motor including fitting is a hefty £1200 + bill.
Has anyone changed the motor themselves & can shed some light on how to do the job myself to save a whopping £830 labour bill please…videos or pictures would be appreciated

Many thanks, Snowy1957.

I’d get a second opinion, VW dealerships are great at mis-diagnosis. I haven’t seen many fan issues posted on the Forum.
The resistor issue is well known, have a Search and you’ll see how it can be avoided.
I can’t think of a reason why the resistor unit / fan motor would cause faults with each other.

Thanks for your reply, very much appreciated.
I was sceptical of the diagnosis from the off & predicted the fan change to my wife before the van went into VW !?
I have looked & seen loads of resistor threads, do you have any recommended threads on how to potentially avoid the resistor blowing ?
Once again I’m very grateful for your help & advice

Don’t use fan speed setting 1, use setting 2 or above.

You’re the 3rd person (2 electrical mates) who’s made the same remarks since I’ve started digging on this problem
Thanks again

The fan motor can cause high current draw if it is starting to seize due to tight bearings, this high current can lead to higher temperatures at the resistor pack leading to the thermal fuse blowing. That said I have not seen any reports of the motor being faulty on the forum that I remember in the last 7 years.
I suspect that it is a money grabbing exercise on the part of the dealer as usual.

It’s also possible to repair the resistor unit, the thermal fuses cost very little (ebay etc).
Use a strip of lead as a heat sink to avoid fusing it when soldering in place.

I use locking medical forceps for heat sensitive electronic components - bonus is that they hold things on place at the same time.

my thoughts exactly…sadly.
