    Hi Chaps
    Just noticed tonight my heater blower is only working on speed 4. I’ve got the manual Air Con, rather than climate. All other functionality works ok, just nothing blowing out until you select the fan blower at speed setting 4. Anything obvious to check? Any known issues?
    Thanks

    Sounds like a blown resistor (s?). Warranty job

    Seems to be becoming a bit of a common issue this one, the fan blower consumes a constant current and if you set it to speeds 1/2/3 then theres a resistor that takes part of the load to slow the fan down
    Its separate from the heater/blower control unit so not too major to change, are you still under warranty ?

    Just googled this picture, looks like a thermal overload cutout on the tip but not sure what is under the cover, repairable or disposable component ?????

    List price is £43 + vat

    That looks like the one @Pauly , 4pin including thermal cut-out.

    N24 - Fresh air blower series resistor with overheating fuse

    fed from -

    J301 - Air conditioning system control unit

    restive load for blower motor stage 1,2,3 and direct feed for stage 4.

    Thanks Guys. Just been Google’ing for the last half hour it certainly looks like that. First MOT next week and warranty until 15th December so looks like a happy ending for this. Is this the same component located under/behind the lower passenger side glove box?

    Update - blower resistor pack confirmed. Part on 7 day back order. Glovebox out and easy access to swap. Dealer said they’d seen a few popping between the 2-3 year marker.

    See if your dealer will work a goodwill repair? Seems be be a known problem. Worth an ask?

    Can you remember the value of the fuse? I have a feeling this is going to be a regular issue on this forum for the foreseeable future and if it’s the fuse that’s the issue rather than the actual resistor pack, this could be a nice cheap fix for members whose vans are coming out of warranty.

    I still have said item somewhere will dig it out and try to locate its value then post up result of fuse value

    Wow a bit of googling shows it’s been a very common and longstanding Transporter problem for years. The old T5 forum is full of loads of discussions, some finding that replacing the fuse solved the problem, some finding it didn’t and needing a full resistor pack. Other posters pointed out that the thermal fuse is there to pull the power in the case of the motor jamming or stopping working, a very valid point as if that’s the issue then replacing the fuse would just cause it to blow again.

    Anyway, a couple of useful videos, again thanks to links in the T5 forum (not transporter specific but it looks like VW use the same kit across all their vehicles, just the access to it would change)
