#8196 of 8333 Climate Control Screen Blank by eagle3 Apr 21, 2008 (2:23 pm)
Yesterday I got in my 95 LS400 and, after starting the engine, noticed that my climate control screen was blank. Thinking I had accidentally pressed the OFF button earlier, I started pressing buttons, ALL OF THEM, and nothing happened! I tried the fan, the temp up and down buttons, the A/C button, mode button...the screen remained blank. I am hoping it is just a fuse. I have looked at the fuse cover diagrams, but saw nothing that says anything about climate control or A/C.   I thought maybe this has happened to someone on here before. If anyone has any ideas what my problem could be, I really would appreciate any help. I live in Georgia, and it is already getting too warm to be without my A/C!

Replying to: eagle3 (Apr 21, 2008 2:23 pm) I have a '99 LS, equipped with Navigation and the screen in my car has "all the eggs" in one basket (climate, nav, radio, etc). I too have experienced the "blank screen" or more accurately, the "grayed out screen" where nothing works and nothing responds to commands from your fingers.   My dealer simply told me to "reboot" ie turn the car off and restart it. I have had to do this maybe a half dozen times in the last year and it worked every time.   BTW, if this does NOT work, then you are looking at some expensive "module" replacements to your car. I do not think it is a "fuse" problem.   I am unhappy that "all the eggs are in one basket" on the touch screen and now I just cross my fingers everytime I start my car.   Good luck and I hope I have been some help.   Mike in Missouri..........

Replying to: mikeyinmo (Apr 21, 2008 2:40 pm) Hi Mike,   I tried the reboot thing but it didn't work. My 95 is not one of the "all eggs in one basket" model. My Radio/CD,etc. has a different screen below the A/C,heater screen, and of course I don't have Nav. I sure hope it is not a bad module. If anyone else out there has any ideas please let me know.   Thanks for the response though, Mike.
#8199 of 8333 10% Ethanol in the gasoline by famwald Apr 23, 2008 (6:01 am)
This week I notice all the gas pumps have a sign on them stating that all blends from the pumps contain up to 10% Ethanol. I usually burn premium Shell gasoline, but even the Amoco pumps have a similar notice on them.   My question is this: what will the 10% ethanol do to the engine of our '05 LS430?   I've searched the Lexus forums and can't find an answer. Thanks! Replies to this message: nvbanker (Apr 23, 2008 2:40 pm) famwald (Apr 24, 2008 2:34 pm)
#8200 of 8333 E10 is fine. by vcheng Apr 23, 2008 (7:51 am)
But stay away from E85 or any other blend with more than 10% ethanol.

Replying to: famwald (Apr 23, 2008 6:01 am) I always burn Shell V-power premium as well, but don't worry. The LS will handle the 10% Ethanol without a problem whatever. It's built to handle much worse, but don't try burning the E-85 corn junk in it. That will turn on your check engine light. Replies to this message: famwald (Apr 24, 2008 2:34 pm)

Replying to: nvbanker (Apr 23, 2008 2:40 pm) Thanks for the reply. My dealer said to avoid, but they must have misunderstood and thought I ran across the E-85.
#8204 of 8333 Re: 93 Lexus LS 400 White Smoke from Exhaust [93lexus] by melissac3 May 26, 2008 (6:46 pm)
Replying to: 93lexus (Nov 24, 2006 3:44 pm) had the same problem with my lexus and found out that it was the air control valve at the side of the power steering pump. Took off the two hoses and plugged up the power steering pump and then capped of the two hoses at the intake and never had the problem again. If your having any loss of power steering fluid i would bet that this is your problem. lexus.com site has step by step instructions on how to fix it. Its a very cheap fix costed me about 2 dollars to fix.
#8205 of 8333 Air filter 2001 ls430 by ckennedy May 27, 2008 (9:57 am)
Anyone know where the engine air filter is located? Mechanic started rattling so some numbers and I said that I would do it. Do I need to go with a K&N type air filter or can i just go with one from like lexus-parts.com?
