LSbr

New information: 1. I have found that the problem goes away after 1-2 minutes of starting the engine. Then everything works fine while I am driving. But when I shut the engine off and then later start it again, the problem comes back... then goes away again. 2. Something that might have caused it - a couple of weeks ago, I removed the center console cover to fix the front and rear cigarette lighter/12-volt charging port. Maybe I tugged on a part of the wiring harness that goes to the climate control panel? Maybe it's a coincidence? Thanks for any input and advice!

Hello, I have driven a pre-2000 LS400 for several years and am impressed by its durability and long-life. Also by the good values for good-condition LS400s on the used market. Did Lexus make any crossovers or SUVs that are especially good values used, in the way that the LS 400 is? Maybe some are low-priced because of a particular problem that can be fixed? Thanks!

I have read through the climate control diagnostic and repair threads such as this one on codes. However, I have an issue that I haven't yet seen described. Intermittently, some buttons on the climate control panel stop working - the rear DF won't turn on, the driver's side temp control will turn the temp up but NOT down, and front defrost only works in auto mode. Then after a while, I will start the car up and it works again. One time when it was not working, I shut the engine off, restarted, and it worked again. When I ran the diagnostics, I got two codes but got a beep with both so I think it means it's not a current problem: 21 (the solar sensor one that I understand is normal to get when it's dark) 24 (and for this one, I have not yet seen any description for it... the guides skip that number. When I ran the fan and door actuator diagnostic, all seemed well. Also I just replaced the cabin air filter just in case. I understand that the climate control control panel shares the same power source/fuse as the front cig lighter, and one time the control started working again when I removed a bluetooth/charger plug that was in the lighter. But probably that was a coincidence, and the problem still happens with nothing plugged in. Any advice? Is this worth replacing the control panel, or should more diagnosis be done first? Thanks, -Tom
