Help! R33 S2 Roof Light Switch

[Ben r33 s2]

Hey guys so my r33 switch light dims when i close the door rather then turning off! And when i open the door the light brightens anyone else had this problem! Issue cause its snnoying having to turn the light on when getting inside the car so i can see at night!

They all dim when you close the door. I don't get what you mean by the light brightens when you open the door? Does the light turn on straight away or it takes a while to get bright?

It sounds normal to me.

[Ben r33 s2]

When i close the door the light goes from bright to low but stays on? isn't it suppose to turn off when you close the door?

When i open the car door the light is bright when i shut the door its brightness reduces but doesn't turn off could it be a fuse?

Yes

[Tommy Kaira RL]

It's supposed to go dim

[Tommy Kaira RL]

Until it turns off

[Ben r33 s2]

How long does it take to turn off?

[Ben r33 s2]

The problem is mine doesn't turn off it dims but stays on

About 10 seconds. I will look at a wiring diagram and see what I can find. It could be high resistance across your door switch or the control module.

Cheers mate!

I noticed someone has put a 15a in the stop lamp fuse when it should only be a 10a any ideas what the stop lamp fuse is for?

[MBS206]

It's the lamp that comes on when you're stopping... Pretty self explanatory...

[MBS206]

Also interior light has three settings, "Off", "On", "Door", make sure it's only set to "Door" and not "on" all the time...

If at "On" it may not be full brightness as it may have not so good of a ground, when the door open it brightens as the door allows a better flow of electricity.

[Ben r33 s2]

Yeah i had it switched in the middle wich is door its a wiring problem i checked the fuses!

[Ben r33 s2]

Any luck with the diagram?

Replace the globe/s or LEDs and while your there take the whole unit out of the roof. While out make sure all the contacts are fine.

- Disconnect the wiring harness from the back of it and then re-insert it. You could quickly clean the contacts it plugs into.

Taking it out is easy. Gently pry the clear plastic off. Inside is 2 screws - remove. It'll drop down. Unclip it. Clean contact points and replace globes.

Clip together and test.

2-5 minutes.

^^^^ That would help if it didn't work at all. The light does come on so that proves the circuit is working and the contacts will be clean. If the contacts were dirty then you would have no light at all

Hope this helps does it turn off once the car is started or the key is in.

I still believe its the entry control unit

There will a constant 12v on one side of the globe and the control unit will supply the other side with a negative via the doors which has to go through the C/U
