How to Replace the Heater Resistor

[piperdave]

So Guys, just need a little re-assurance before i attempt this....I have lost stage 1 blower, that is the slowest speed. The rest are OK at present.

Car is '96 V40 Ph1.

Is it likely to be a resistor? Or something else?

Great guide as always.

Thanks for any advice......

Dave

Hi gatos, change heater resistor, but fan only works for a few seconds then packs up. Great set of pictures. Also tail gate won't open any ideas.
Cheers.

Never heard of the heater stop working after a few seconds. Does that happen in any temperature setting or on automatic?

With regards to the tailgate lock, you mean it does not lock unlock with the central locking, or that you cannot open it at all?

Sounds like a blocked heater matrix?

The heater resistor is located in the passenger's foot-well behind the glovebox.

First of all, you need to remove the sound insulation cover under the glovebox. To do this, you need to undo two screws (philips head) located where the yellow arrows are pointing. You can see a close up of the screws highlighted with the yellow circle in the next image. Also remove the plastic cover highlighted in the green circle. You will see why later.




Remove the cover and you can now see the connector plugging in the resistor.


You need to remove these two screws securing the resistor. The bottom screw is very easy to undo, but the top one is harder to get to.


Undo the two screws (marked by the red arrows) and pull out the glovebox


Undo the three screws (yellow circles) and undo the 10mm bolt (red circle)


You can now pull the main console forward just enough to gain access to the top screw


Undo it and pull out the resistor.


The part number of the resistor is 30864189
