Lighting Heating controller

Hello,

so I start the first thread in this part of the forum :D . I have a problem with my heating controllers. Since I have canged my instrument panel in May (it had several cracks) the lighting of them doesn´t work. The light bulbs are OK. Is there any cable at this white thing where the controllers are fastened? And if so, where exactly it must be re-inserted at this white thing?
Here an picture of the thing I mean (in the red circle):

I hope it can be fixed easily, I don´t want to see my interior in this way again :hehe: .

Gruß Thomas

If I understand correctly, you changed your dashboard and since then the two bulbs which are connected to the ventilation circuit board don't work anymore? Right? Did you check that you didn't break or damage a conductive trace?

Yes, I changed the dashboard. Everything works like before, the only thing that doesn´t work since that time is the light. Hmm, I had only pulled the controllers and took off the cover (two screws solved). That was all that I have made with the ventilation circuit board. I dont know if I have damaged any conductive trace, but I dont think so because I didn´t touch the front of the board. Can I also have a cable demolished? Where does the electricity for the bulbs come from?
Oh, very bad English, I know... but I hope you can understand it. It´s difficult to find the right words with this technical things. But the German people didn´t have any idea what the problem is, so this forum is the last chance before I must go to PEUGEOT-garage (but they also have no ideas with those old cars :pleur4: ).

Gruß Thomas

You are talking about lights that don't work but are we only talking about the ventilation bulbs? If yes, there are only two bulbs and both are powered with the same cable. Actually, there is only one cable that powers the circuit board and it's a 5-pin cable. If you remove the ventilation plastic, you'll be able to see the connections and the first two power the bulbs, no matter the circuit board you have (B or C). I took a picture of my previous circuit board to show you. As you can see from the picture, I circled the connectors that power the bulbs:

Make sure the 5-pin connector is correctly inserted from the back. If it is, and if you have a multimeter, turn the headlights on and control that you have power at both connectors. In order to have access to the back of the circuit board, you don't need to unscrew it, just remove the plastic cover which is between the ventilation plastic and the stereo and which can't be seen at first. It is situated here:

PS: I posted a message in our French forum so we can think with more than two brains. The more we are, the faster your problem will be solved. ;-)

I also changed it on my 309 bestline, but I have some electric trouble too... but because of a short cut I think (my car was stolen and a part of the cables is brocken).

For your problem, are you sure that the wire which goes on the top of the dashboard, and ended in the compartiment of the right, permits to lighten the light that it includes?

If not, the trouble seems to be here.

Good luck ;)

If I understood correctly what Thomas told us, the only bulbs that don't work are the ones attached to the ventilation circuit board.

Hello,

thank you very much for your answers and your efforts. I will first check the cable which brings the power to the circuit board for the bulbs. It is possible that I had accidentally removed it when changing the dashboard. If not, I will use the multimeter.
I register again if I have made it.

So no news from you... Does it mean the problem's solved?

Hello,

I had no time the last weeks - I was just only at work. But today I had time to look for my problem - but I was unsuccessful :( . I took out the radio and looked for a loose cable but there was none to be found. Then I took off the panel to get to the board, but it was very closely and so I could see nothing. There were the Hoists and I saw a black cable that came from the direction of Speedo, but I think it was not loose. So it should work... I have also checked the fuses but they all were O.K. I think I have to live with the problem :snif:

Hello Thomas!
You don't need to remove the stereo. You can have access to the connector here:

You just have to remove the small plastic part and you'll see the connector:

The first two wires are the ones which power the bulbs. You need to look at the diagram SRDTurbo posted.

Man, am I stupid. As I analyze the half-car and still need to take out only the little plastic bezel. So I couldn´t see the connector, I didnt´t look at this place. I suspected a loose connector behind the radio had come down.
Thank you very much for your tip and pictures, so I will look again next week when I have time. I also will use the diagram SRDTurbo posted.
