greetings all:

need your help. my 93 400LS 's trunck will not open with the key. The key will not turn in the lock, either way.

however, I can open it with the inside switch. seems to me I somehow triggered a security meanure.

how do I defeat it.

thanks

frank

they should be backlighted when the parking lights are on. when you put parking lights on, do the controls on the dashboard dim?

no they don't. Appreciazte your helping me track this down.

so if i say that your buttons NEVER light up i would be correct?

Gosh, I sound like such a potato. I assume that the buttons are backlighted, as they are in other cars. In mine, never. In any mode. the leds within the buttons however are.

Also a question: is lexus the only car company in the 90-s that did not put a light in their console storage area. can't believe there isn't one there.

Thank you for your help.

so lcd lights are off in both parking lights mode and headlights mode?

when the ligts DO go off, how are the lights on the buttons? are they also off or are they on?

here is the sequence i would like you to do

1. monitor the lights when the key is in the acc mode and lights switch is in the off mode. and let me know the status of the lights for LCDs and for the buttons on the climate control and stereo.

2.turn the lights switch to parking lights mode and report the same

3. do the same for the headlights on postion of the switch.

Okay, thanks for the reply.

In and ACC mode, the LCD lights are on, the leds are off for the fan speeds and the air flow modes .. but no background lighting for the overall buttons.

In the parking mode, the same, LCD lights are on, the leds are on for the fan speeds and the ir flow modes .. but no background lighting for the overall buttons. the glovebox light now works. but no background lighting for the overall buttons.

When the headlights come on, the lCD's for the radio and the clinate control go off, the led's stay on, but no background lighting for the overall buttons. the glovebox light now works. hmmm

I appeciate your help in this matter. driving at night, trying to figure out the heating system is very tricky. that backlighting of the controls is really impirtant.

Hope this helps.

by lcd displays going out you mean all the information disappears from the screen or you mean the backlight is out? is it only for headlights or when you put your parking lights on? when u put just the parking lights do all buttons light up?

what happens to lcd when you put the parking lights on?

Okay;

checked when the parking lights go on ...

the display lights go off ... also, the glove box.

Headlights on ..display and glove box lights off.

Hope this narrows it down some. thanks for your help.

Greetings form Florida:

just got an 95 LS 400 and have noticed that when I turn my headlights on, the LCd displays in the radio and climate control go out. The light in the glove box works when I open it ..but when the headlights are on, it goes out.

is there a relay or something that needs replacing?

can some one guide me? if it is a relay, where is it located and the part #, if possible

thanks and warm thoughts
