Td5 switch info


Recommended Posts

Does anyone know if any switches are interchangeable between the disco td5 and the def td5,

E/w

Heated seats

Rear Demister

Front heated screen

Cheers ross

The TD5 Defender electric windows switches were lifted straight out of the pre-facelift Discovery-2 (1999 - 2002), and are exactly the same part numbers (front windows switches only, the Discovery-2 rear windows switches are different, and use a different coloured connector).

The front electric windows switches from a facelift Discovery-2 (2003 - 2004) will also work - but, they're 'Black', whereas the pre-facelift Discovery-2 and Defender ones are 'Ash Grey'.

The TD5 Defender heated seat switches were also lifted straight out of the pre-facelift Discovery-2 (1999 - 2002), and are exactly the same part numbers.

The heated seat switches from a facelift Discovery-2 (2003 - 2004) will also work - but, they're 'Black', whereas the pre-facelift Discovery-2 and Defender ones are 'Ash Grey'.

The Discovery-2 heated rear window (HRW) switch shares the same switch front as the Defender (pre-facelift/facelift colours, as above) - but, switches differently.

On the Defender, the HRW switch is a latching, live-switching switch.

On the Discovery-2, the HRW switch is momentary, earth-switching switch, working in conjuction with the Body Control Unit (BCU).

They also use different coloured (and keyed) 5-way connectors -

The Defender uses the Blue 5-way connector.

The Discovery-2 uses the Black 5-way connector.

The Discovery-2 and Defender heated front screen (HFS) switches share the same switch front (pre-facelift/facelift colours, as above), and are electrically identical, they are both momentary, earth-switching switches - but, they both use different coloured connectors -

The Defender switch works in conjunction with the timer relay, and uses a White 5-way connector.

The Discovery-2 switch works in conjunction with the BCU, and uses a Green 5-way connector.

There may also be differences between the moulded keyways on the switch's bodies - but, these are easily removed with a sharp knife.

Wow you are the go to guy and switch info thank you very much , I've been a little confused regards heat seat switches as come seam long and others seam tall if that makes sense I'm after the taller style but the £50 on line.

This also explains why the disco hrw switch will not run my defender , so the defender switch you have to physically turn on and off? Where as the disco one is momentary ?

I'm looking at buying a disco switch panel which has 4 e/w switches and 2 heated seat ones . So these will work in a def

The TD5 (Defender and Discovery-2) heated seat switches are 'portrait' -

The TDCi Puma heated seat switches are 'landscape' (and a lot cheaper than the TD5 type) -

The heated seat switches (TD5 and Puma) are wired the same as the Defender heated rear window switch.

So, you could use the Discovery-2 heated rear window switch front on a Puma heated seat switch.

The Discovery-2 front windows switches and heated seat switches are exactly the same switches as used in the TD5 Defender - so, will work OK icon_thumbup.gif

I know this is a very old topic, but I hope someone can help.

BTW, this is my first post here - I'm active on other forums but it's nice to meet you all!  I'm currently fitting a genuine Puma dash into my 2002 TD5 HT and going through all sorts of fun and games, although 90% there now!

My challenge is that I only have 1 spare switch free on my new Puma dash and I'd like to fit a single rear wash/wipe switch. I currently have a rear wash/wiper running from a single Carling switch.

The Pumas appear to have separate switches for rear wash and rear wipe, but I don't have the space for both.

The Disco 2 has what looks like a single switch (YUE000210PUY) so I am wondering if that will work and then I can replace the bigger switch face with one from a Puma switch?

Any help is greatly appreciated!

I converted my Td5 to a single switch for rear wash / wipe - but I can’t for the life of me remember how I did it. It’s a momentary switch - one press activates the wiper and holding it down the washer jet. 
 

I’ll see if I can find anything on it.

That Discovery 2 switch won't work for what you want it to do.

The majority of Discovery 2 switches (including YUE100600 (pre-facelift) and YUE000220PUY (facelift)) switch a BCU signal wire to earth.

The rear wash/wipe functions are then initiated by the BCU (Body Control Unit).

As an aside, switch part numbers that have a PUY suffix, are Black.

Switch part numbers that have no suffix, or a LNF suffix, are Ash Grey, which is the correct colour for pre-facelift Discovery 2 and Defenders from 2002 to 2016.

It's easy to make the standard Defender rear washer switch (YUE000070LNF) also operate the rear wiper - however, the wiper (and washer) will only operate for as long as you hold the button down.

Another option would be to add additional switch carriers.

A member on the Defender2 forum (mcma1) has had some injection moulded, in 1-way, 2-way, and 3-way -

The ideal place to fit them, is below the stereo -

Worth saying that’s never been an issue for me.

Thank you all for your help.

I only have 1 spare switch on my double din panel so I think the suggestion of combining the function might be the best option

@PaulMc from your earlier post am I right in thinking that I can use a Disco TD5 heated front screen switch in a Defender TD5, but I can't use a Disco heated rear window switch because they work differently?
