Hi PP users, Have a problem with my interior lights on my 2000 prado 95 series, they don't work when you open the door, they work manually when you turn the dome lights to on. Have checked globes, door switches, fuses and have diagnosed the problem as possably the Intergration relay is not working according to a wiring diagram I have.
Questions are Right diagnoses?, where is this relay?, what does it look like?.
Thanks regards Graham
