  1. Bump and update: I still can't figure this out. If I disconnect the right-most wiring harness of the climate control unit (as you are looking at the back of the climate control unit), the backlight stays on all the time and does not change status (i.e. dim or brighten) if the headlight switch is switched. I can see that backlights are getting power using a voltage meter when I check the cigarette lighter harness (oh yeah, the light for the ashtray is also out in any condition). All the functionality of every button and switch works. It's only the lights for the buttons that do not come on when the headlights are on. I called Lexus to see if they might offer some free on-the-phone assistance and they told me to disconnect the iPod system which I did to no avail. Could I have shorted something in a component such as the climate control unit when I disconnected it with the negative battery terminal still connected? I hope not since that seems like a very weak design. Am I missing a backlight control button? I've checked the obvious fuses but maybe I need to check each and every one. Man, this is frustrating. I should have paid the $100 bucks to get the iPod system installed. Please any help is appreciated. Anyone have a wiring manual?
  2. I was able to download and the 2005 ES330 FSM but it does not have anything on the electrical system. Does anyone have the electrical portion of the FSM for a 2005 ES330?
  3. So, I installed an iPod adapter in my 2005 ES330. All went well and it works just fine. Except that the backlights on the climate control and radio and rear sun visor all seem backwards now. They are lit when the headlights are switched off but the backlights are off for any other headlight condition. One thing I did not do was disconnect the negative terminal of the battery before I disconnected everything else. Did that screw things up? Is there an easy way to "reset" the lights? Thanks in advance. Rich
  4. I am going to purchase my ES330 after the leasing period. I am looking at a few upgrades: 1) Upgrade to the Nav system - I know I can get the map update but is there any other upgrades that change the look and feel to be more in line with what is currently offered? I'm hoping there is a software upgrade that changes the graphics on the screen. 2) I had XM installed but the display on shows the first 10 characters for the title and song. I know XM broadcasts the full set of info (i.e. full artist name and song title) so I'm wondering if anyone bought a different XM radio that will display the full name. 3) iPod connectivity - has anyone installed an iPod system with Nav and XM? What system? What functionality did you lose (I hear you lose the 6 CD changer)? Thanks in advance. Rich
