Hi all

I know locks have been covered a lot but I can't find the exact answer.

Had drivers door lock replaced with non genuine new unit today. Works fine but noticed interior light not on when drivers door is open nor is the symbol on the dash. I assumed micro switch failure.

However, the car doesn't recognise any door is open when it did before today. Similarly when a door is open, the light in the bottom of the door illuminates.

This tells me that it's not the micro switch?

Basically I'm baffled. Is the new lock the cause of every door not triggering the interior light and door open symbol or is it something else. I have read the courtesy unit could be of fault but can't find clear instructions on where to find this.

Ang pointers would be appreciated. Thanks

Does your boot switch work ? If not, the fuse might be blown.

It unlocks on the key fob but if I press the drivers 'all doors' unlock button - it doesn't unlock.

 

Looking it might be fuse 5 to check so will do that thanks.

I think it is fuse 4 IIRC.
