Back Light Missing

[Bluesman]

Is it easy to sort the back problem behind the interior temp indicator. Temp indicator still works but cant be read at night. Mike.

It requires the removal of the centre console and then dismantling the unit from the back this then reveals the lighting board that as small bulbs in lock sockets.

It is not difficult but care as to be taken during the removal of the console as not to scratch the veneer and uncoupling the wiring.

The facia screws are countersunk along the edges but be careful when taking them out as the switches are all spring loaded and to make sure they don't go all over the place remove the facia evenly with the console face pointing upwards.

Many thanks Ambermarine. Regards Mike.

I Have taken some pics of the spare unit I bought when I first got the Mark 4

There are only 8 screws 6 are countersunk and two are domed .the pic of the side is mirrored ,the bottom has no screws and is clipped in place

Thanks to Mark, Ambermarine for your brilliant posts, much appreciated. Mike.

To be honest there's a bit more to getting at those bulbs than I imagined,I find it incredulous that what should be a simple task requires the virtual dismantling of the unit.

On the backlighting for the mark1 it involved the removal of the facia to the console which is what I thought was the case here,anyway I got you halfway there and I am sure you would have found the rest of the exercise a breeze.

Ps Having studied the pics and description further I have come to the conclusion the dismantling of the unit is not required The front facia will come off and the ribbons can be unclipped as it brought out from the top it is then the dismantle of the facia to get at the bulbs as described

Many thanks Ambermarine I will let you know how I get on. Do you happen to know what bulb fits in there? Mike.

The backlight bulbs I replaced in my 1990 mark 1 were part no 83119-24530 and I bought them from Lexus in Edinburgh.

They are actually clear but supplied with a green plastic shroud,weather these will fit in the 1998 console is not something I can verify but I am sure you could get the part number from Lexus.

The pic is of one of those but as a round base were as the one in the console looks square.

Many thanks Ambermarine. Mike.

I Have checked the toydiy site and the part numbers showing for A/C control lighting are as follows.

1998 Lexus ls400 europe rhd

Bulb LCD 14v 1.2W 5 no part number 90010-03012.

Bulb knob (switches) 14v 1.4W 5 no part number 90010-03013.

That tallys with the bulbs in the console and the LCD are the ones required.

They show as being 3 euros each.

Hope this helps.
