Hello guys. I'm new here and I just bought a Discovery 300Tdi 1994 3 doors with 250 000 km.

The disco works really well nothing to point, but sometimes when I use the turn signal/light switch the front windows go up, any idea or tip where I can check?

Thanks in advance,
G

hey guys, any idea about what is the function of these two relays and the gray box?

 

Doesn’t look like your picture uploaded?

This may be obvious to you, but when you’re engaging the turn signal you’re completing the turn signals circuit allowing electricity to flow. The circuit your window motor uses is obviously conducting electricity from the turn signal’s circuit when the turn signal is operating. Two circuits are connecting that shouldn’t be. Did you try looking through the electrics manual for the D1? Find the diagrams for the turn signal and window motor and see if there’s a point where the two circuits may interact or at least become physically close to one another and then check faulty wiring?
