A/C Centre console heater switch

[taroz]

Does anyone know where I might be able to find a heater switch for the centre console - the two step switch for the heater blowers - but for a UK A/C model?

From my reading there appear to be different switches with the non A/C part number 131812 and the one I think I need being Stanpart 151243.

Tried the usual outlets but so far no-one seems to know about it.

I saved this from someone



Stag AC Switch mode

Bench testing it I have:
In the OFF position - no continuity between any poles
In the LOW position - Continuity between poles 1 & 4, and 6 & 7 and
In the HIGH position - Continuity between poles 1 & 4, and 7 & 8


Yea success!! Very grateful to my friend Jerry Benedict who figured out how to modify the switch!!
If you have a standard switch you need to take it apart and either remove the full length continuous copper strip and cut it into two, or if you have a small Dremmel tool you may be able to grind it out in situ in the switch back.
Once you have done that, squeeze BOTH sides of both copper strips together. This will make reinserting the toggles much easier.
Move the switch into the first position (LOW SPEED) and insert two 5/16 hex/Allen keys into the back of the switch back and push them through so the show out the front of the box. Use these to separate the toggles, then keeping the switch steady insert it into the back box gently keeping everything aligned.
Remove the hex/Allen keys and us a small screwdriver to prize the terminals apart.


Hope it helps

Is that the modified switch? must have to do other things with the wires for that to work?, yes it can be modified but ..

original A/C switch works as follows:-

In the Off position there is continuity between 1&2 (If the A/C is switched on this energizes the speed relay which grounds C2 and runs fans in series to make it run at low speed)
in low - continuity between 2&6 (also sends 12v to speed relay. again it runs the fans in series)
In hi - continuity between 7&8 (Speed relay is de-energised giving 12v at C2 and the ground from 7 to pin 8 grounds both fans and they run in parallel)

I had the circuit and a possible work around in this post

Hi both,

Many thanks for your suggestions. I’ve got the blowers temporarily wired to a simple switch connected to a live feed - so have full blast fans when needed.

Hi Terry,

It was that useful article that got me the part number that I’m hunting. I suspect finding one will be like a search for the S-9467 spanner!

Thanks,
Tariq
