I have a problem with my 01' GS4 Navi:
First I noticed that top row "AC" button lights are NOT after starting of the car ("Auto", direction, defroster, etc)
Then, when I go to "Climate" mode, onscreen AC control buttons don't work: they are not disabled (greyed out) however, upon selecting, have no effect on AC. In addition temperature (outside/inside) numbers are not displayed. (see the picture below)



To my surpise, though, AC is actually working: I can press "OFF", "AUTO", or any other buttons from the top row and get the expected result.

Also, the trip computer's numbers are gone!!! WTF????


Any idea what it can be caused by?

Thanks!

not to sound stupid, but how many miles are on the car?? are you still covered under warranty?? if you are even a little over, sometimes Lexus will still help you out. personally, i would start there. i doubt its a DIY, but maybe a problem w/the screen display itself. i know that on my pioneer head unit, the display is not that great and part of it (the numbers) do not show up whenever they feel like it

The warranty just expired

If it truly JUST expired, I'd still take it to the dealer. There have been dealers that have extended a good will gesture beyond the warranty period, especially if it was recent. Try a few dealers if you have more than one in the area. Also try Lexus corporate. Ultimately, it does not hurt to try.

If someone posts a simple fix, then all the better. If not, try the dealer. Good luck.

Just throwing out some ideas, you might want to try to reset the ECU first to see if you can get everything back again. Since I work with computers and reboot often time is the soution for lots unexplainable issues, I would try to "reboot" your car first. Hope this helps.

Hmmm, reboot my GS? I was already thinking about doing that... I have not found the "reboot" button, though... heh-heh. Are there directions on how to do that posted anywhere?

Thanks!!!

disconnect the negative terminal of the battery and leave it like that for 1/2 hr

To my surprise, "rebooting" of my GS resolved all the problems with the display.

Thanks for your help!

Glad to know, where should I send you the bill now?
