Lexus LS 2007+ :: Rear Seat Controls And Display Do Not Work For Climate Control 2008 LS460L
May 12, 2012
I have a 2008 LS360L with 4-zone climate control. For whatever reason, the rear seat controls and display do not work for climate control. The controls still work for radio, rear seat adjustment and window shades, but climate functions are unoperable.
Additionally, the 4-zone buttons on the nav touchscreen are now missing in the climate menu. There used to be left / right passenger settings and then a button to switch to rear seat settings. These options have all disappeared from the menu.
I can press the 4-zone physical button on dash and manually change temperature settings for driver or passenger by pressing physical driver / passenger temperature up / down buttons.
The only thing I can attribute to this is I had the dealer do a map upgrade to the nav system. All other features / functions work, but the timing is somewhat suspect... They really do not believe this upgrade caused the problem.
Are there hidden menus I may have hit to deactivate this feature?

I have a '13 GS with the Luxury Package that has the rear seat climate & radio controls. I'm not sure if there is an issue or if the system is locked....Of the rear controls everything related to audio portion works correctly...Now if I try to turn on the heated seats, or change the temperature, or blower speed none of those work as they should.

I just bought a 2007 and my Multi Information Display does not work properly on the climate control screen or information screen. ie when you press temp up or down buttons it sometimes works and when you want to change the fan speed and press medium it goes to low. On the information screen no matter what you select it goes to Trip information screen. However the Audio screen works perfectly.

I turned on the climate control this morning when I started the car and tried to change the temperature, then for some reason until the car was warmed up the climate control went to lo and seemed like it was locked there.
Once I the car got warmed up, the climate control worked was normal. It seemed like the increase/decrease controls were locked.

I just got a 2009 570 with rear entertainment, It opens and closes on command when prompted from the front screen and when i use the remote control, it also tilts at various angles but that's all I get from it. it is completely blank. No display whatsoever just tilts, opens and closes. I have a DVD loaded in front. Its a Mark Levinson system the DVD plays fine on the dash screen when I put the parking brakes on but the rear screen remains blank I would call it dead if not for the fact that it opens and closes.

We own a 2008 LS600Hl and love it. I just got the car back from a minor bumper fix from the body shop last week, and my daughter showed me that the armrest controls in the back are dark. Think it could be a fuse, relay or the genius at the body shop had to disconnect something and did not connect something back. If it is simple, I'd rather take care of it, than go back to him again.

My 2005 Ford F-150 Lariat 4x4 5.4l V8. the climate control system will not let me lower the fan speed or let me change the airflow direction. and my heated seats will not work as well.. i looked at the fuse it was good.. and un-plugged the battery for 3 minutes.

Was on my way to get an oil change at my buddies shop. Started hearing a clicking sound. My climate controls no longer will respond. the Auto button is lit up but I can't turn the air off. I get hot air from the vents. When the clicking does stop the system goes back to working order. My friend checked it out and says the clicking is from the blend door motor.

I just purchased a 2009 LS460l and noticed a really deep vibration coming from the rear of the vehicle. The vibrations occur when I am at a complete stop and attempt to accelerate the vehicle turning to the left or right. Initially, I thought the tires were rubbing (18inch wheels), but after taking it to my local Lexus dealership they seemed confident the vibrations were occurring because my center differential needed to be flushed a refilled with 3 quarts of new fluid (they claimed the fluid was filthy) which is ~$150/quart. The car has brand new tires and all of which were just balanced/aligned.

I know this is a weird post but I am looking for a climate control head unit that does not work. I need the silver covering plate that is part # 55901-24030 that is not damaged.

So I have a PCS fault on my 2008 LS460L and brought it to my local Lexus Dealership....They basically insist that the data controller is/may be causing the PCS fault.
In the meantime, I guess the most probable action is to disconnect the data controller and see if the problem goes away.....

I am having problems starting my car. It takes 5 or 6 tries . It will not turn over it will just click under the hood. I scanned the code and it showed the crankshaft sensor code. Would this be correct or could it be the starter or starter components. It is a 2008 LS 460

I just purchased a 2007 Ls460L. I am happy to be back in a Lexus Ls. I had a ls430 when I joined this forum many years ago. The rear window sunshade keep coming up on it own when I start the car.. It will always goes down when I push the button, but It wont go up after I put it down the first time though.

2007 LS460L; nagging subtle muffled rattle in the rear cabin deck. It turns out that if you remove the passenger side panel in the trunk, whereas you are capable to reach behind the frame and the rear fender panel. There I found a drain hose, neatly wrapped in sound deadening material, but loose enough to rattle around against the outer rear fender panel enough to create that elusive subtle rattling sound.
I simply did a quick fastening job with gorilla "duct" tape, in order to secure the hose to the inner frame of the trunk. This prevents the hose from moving around with "ANY" movement produced by the vehicle over the smallest of bumps to the largest of bumps.
I checked everything from the sunshade, to the speakers, to the subwoofer, to the air ride suspension caps (accessed by removing my electronic reclining rear seats), to securing all hardware in the spare tire compartment, to the middle row seat belt "housing", to the middle row headrest "relaxed position", to the rear center console.
All of this effort only to read another members experience on their 2009 lexus is250 with the "brown/blue box electronic housing" in the trunk behind the panel on the passenger side, where he found his solution by tightening the retaining nuts on the housings bolts that secured it to the inner frame structure.
blue/brown plastic box that connects the wires inside the trunk.

Was driving the last week and happened to look down and notice the display for my climate controls was completely black. They were still running at whatever I had them last set at but couldn't change anything or turn the system off. Pulled into a parking lot, turned the truck off then started it again and everything was working fine.
Couple days later, was driving down the road again, glanced down and now my climate display, stereo display and odometer display were all black but once again everything was still functioning, just couldn't change anything. Turned my wipers on to check those, heard a little click, and all the displays popped back on like normal???? Wipers worked just fine too.
I'm assuming a short somewhere but wouldn't even know where to start to look or if it's even within my limited skill set to try and track down.

Just purchased a 2008 F250 V10 Crew Cab with 64,000 miles. The truck has some electrical issues that didnt show up during the test drive/inspection. It seems that the HVAC head unit causes some interesting things to happen. The most obivous problem is that when you turn the climate control on and turn the fan speed up the CC will not work. If you turn the fan off but leave the HVAC control on CC starts working. At this point you can turn the fan speed back up and everything stays working. Not sure if its related but it also has the printer noise going on behind the dash which Ive read is the one of the blend door actuators going bad and the keyless entry pad will not accept a personal code(everything else works on it, factory code, lights up, two button lock). Any checks?

From time to time, climate control will stop working. Buttons are not lit up or responsive, fans do not work, and computer doesn't show outside temperature. Problem can last a day, an hour, 10 minutes, or any other time frame. Most of the time once it stops working it will not start working until left parked and locked overnight. Sometimes when we start driving it would all of a sudden start working on its own. This has happened during multiple seasons and multiple weather conditions.
I took the car to Lexus dealer who decided it would be a smart idea to replace the whole climate control unit in the dash, well this past weekend the problem occurred again with brand new climate control unit in place.

I have a 2008 LS460L and the front driver's and passenger's windows have wind noise, sometimes worse than others. I also drove a 2007 which experienced the same problem. It is still under warranty, but not sure if there is anything which can be done. Not sure how a car with doubled panned windows can have so much wind noise.

My 2008 LS460L blows cold air on cold days/nights when the engine is idling. Raising the RPM to about 1500 causes heat to start to flow out of the air ducts. I also hear a gurgling sound behind the dash when accelerating normally from idle. The water pump was replaced by Lexus in late April 2014.
I have checked the coolant reservoir (engine cold) and found it to be slightly below the "LOW" coolant level mark (not empty). It would seem that since the feed from the coolant reservoir is on the bottom of the reservoir, as long as there is some coolant in the reservoir, the rest of the system should be full.
All things considered, are the two issues (no heat & gurgling sound) more likely to be caused by low coolant in the system, the relatively new water pump, or something else? BTW, what is the proper method to top off the coolant in a 2008 LS460L? Are there any special bleed ports for eliminating air pockets?

RX450h Climate Control ... This is annoying and all my riders complain about the A/C Auto mode on this car. Here is the issue in Auto Mode with the inside temp set at 72 degrees, and the outside temp is cold anywhere from 55 to 65 degrees the A/C always blows cold air into the car. I can never get heat to flow into the car. The manual says that auto controls the a/c flow, fan speed, and vents like auto in almost every car. What is wrong here? The A/C is always on blowing cold air regardless of the temperature set inside the car. To me it seems that the temperature setting for both passenger and driver do not work.
