Hi,
i have one problem with my XC60.
The internal ceiling light not start .
I have change the fuse n 6 (7,5A) in the box near the passenger, but when i put a new one is broken immediately,one short circuit in somewhere place....
I have open all the internal lights box front and rear and also the rain sensor near the internal mirror i have open all the connectors but nothing always short circuit....
Any idea where i could look ?
I have bought the used car and it was broken before that i bought.....
THX

 

It may be a light bulb was replaced and it is the wrong bulb and it is drawing more power than a correct bulb.

This is just a guess, but I've made this mistake on previous cars so I would check that first.

 

Ok i Will try to control THX
