Hello,

Both switches for the Foglights and the rear window heating doesn’t work anymore. Unless I press the switches (much to!) hard, but than they only stop working when switching the engine of.
I think a little spring isn’t working anymore in both switches.
‘I trued to separate both components of the housing (one sliding in the other) by carefully “tilting” the outer component over the 4 tabs in the inner component (2 tabs on te upside, 2 on the underside, as you can see on the picture).
I could separate the switches for windows, sunroofs, air recirculating and Air/Con by hovering one component over the 4 tabs on the other, but now… great misery and great mysterie !
What d I wrong ? Is there another tab or other that I haven’t seen ?
(and the green bulb for illumination and the red one for functioning are working)

Much greetings from Belgium,

If you are opening the switch on the left in your picture you must first remove the bulbs (orange and green bits) Carefully pry them up.

Very fiddly bit of work these. I used tooth picks or pins to separate the four latches, then a pick tool with a sharp point to work the guts out. One of my trucks had been splashed with Coca Cola which is very sticky stuff when it dries. I suppose we could soak the switches in warm water to loosen things up, so long as they get dried well later.

I toured the Fluke factory in Seattle years ago as a college student and was quite surprised to find out all the circuit boards got washed in a "dishwasher" after they were assembled.

 

Hello,

Thank you very much for the information !
So yesterday evening both parts from these switches where separated without problem (after first taking out de red and green bulbbase !)

But..; the tiny “hooked rod” and the smal copper blade which hold one side firmly against the inside from one part are absent !
I looked everywhere in the switch with the light from my smartphone, on the floor, but nevenwere.
But for about 3/4 months these switches where working normal.
Of course I can “remake such hooked latch by adapting a paperclip with exact the same diameter.
Who can explain to me the working from these hooked latch ?
Has anyone a good advise for me for this repair ?

Green : one end where the hooked latch should be ; Blue : other end where the hook “move” in an triangulair canal.


! THANX !

Hello,

After removing both lightsockets, both parts of each switch were carefully separated. Both parts, springs and copper contacts were full of grease, a kind of green looking paste and dirt. So I cleaned all the components carefully, the last dirt with a little little tiny jet of 4WD…and both switches are again working as before, fine !

But in these kind if switches the little “rot with a hook” is indeed not used : just pushing in the switch and withdrawing immediately your finger, the switch gives a short impulse to another relais that makes the current flew constantly for making the rear fog light and the rear door heating working. A second push on the switch gives a new impuls to the relais to stop the current flew. (impulse contact, 1st kind)

The switches for Air Recirculation and Air/Con both remain “pressed in” by the working of the rot with a hook. They remain “pushed in” as long as the current flew. A second push releases the rot with hook, the switch comes again out to the face of the climate control and the current is switched off. (hold contact, 2nd kind)

The switch for the tail window washer gives contact to the pump as long as you pushes in the switch. In fact in this kind of switch your pushing finger replaces the working from the rot with hook ! (working when pushing in, 3th kind)

In any case I learn every time more and more about my Disco !
