Hi, there's no lights in the swithes and AC control buttons in my 1999 GR SE+ 2.8Turbodiesel.. The instrument lights work fine, also the dimmer switch for the lights. However, all the interior switches are without light... Then when a function (for instance window heating) is activated, the indication is lit, but there are no background light in the switches. This goes for all the switches in the car.. Checked the fuses - all are OK. Any ideas?
