ford212.809 Posted October 11, 2006 Share Posted October 11, 2006 I have a friend with a '97 LS400 and all of a sudden the controls on the climate control dash panel do not function. Any of the buttons that are pushed = nothing. All of the lights and backlights work properly. We have checked all the fuses that apply - I think. Any ideas / suggestions?

blake918 Posted October 11, 2006 Share Posted October 11, 2006 That happened to me one time, and a new fuse cured the problem. I was about ready to pull off the road and cry because it was in the heat of summer when all of the sudden the climate control goes blank. The climate control in my '95 is linked to the cigarette lighter fuse; I replaced the fuse, and I was back in business. The root of my problem was the cigarette lighter, it came loose and would blow the fuse if you touched it. I tightened the lighter, replaced the fuse, and it has been fine since.

Blake, You ARE the man. My buddy's climate control problem is repaired. He found the CORRECT fuse, replaced it and he is back in business. He thanks you and the local Lexus dealer does not like you. Many Thanks from Tennessee. ;) Quote Link to comment Share on other sites More sharing options...
perks2 Posted October 11, 2006 Share Posted October 11, 2006 Hi, I am new to the form. I have a 1993 LS400, bought it wrecked took me about a year to get it on the road. I just love the way it drives the ride is so smooth. My climate control is dead also. It won't do anything. It was working fine and all of the sudden the fan quit and so did the lights on the dash for the climate control no air cool or hot. This happened about a month ago. The lighter hasn't worked for most of the 4 months, I have been driving the car. I was in the process of getting a cabin air filter,when the ac quit. The old filter must of come with the car. It is dried up and looks like brown concrete. Now the compressor motor baring is roaring. I have a few other things wrong with the car, could anyone help me on this problem. I live in Missouri at Lake of the Ozarks and it is about a 2hr. drive to a lexus dealer, to the south. 1hr north to a Tyo dealer. Today I took it to someone local for the roar. I will call him tomorrow and tell him to check the fuse. My husband had checked under the drivers dash for a circut braker. He said there wasn't one. But on the form I read one fellow said it could be that. If anyone knows anything else to check. please tell me. Thank you for this form, it is very informative.

lexusnutt Posted October 11, 2006 Share Posted October 11, 2006 Blake, you are right on about the cig lighter being the cause. I just got the car a week prior and was ready to go for a summer night drive. Mine happened when I tried to plug in my cell phone charger into the outlet. Everything went blank. I also looked for a fuse, but everything was OK. I pushed in the ashtray and lo and behold, it worked! Like the trunk wire, I think the cig lighter wire is too short and wears after multiple pushes on the ashtray. I haven't pushed it since and it's never happened again. I want to fix it, but I don't know how to remove the lighter. Anyone know how to do this? Cheers! Quote Link to comment Share on other sites More sharing options...

Isn't it nice when the problem is from something simple like a fuse! :D I keep a pack of those fuses in my trunk after I went through this.....I can do without a lot of things, but my air conditioner most certainly is not one of them!!!

I wonder if the wire isn't tangled or cut up on something because I don't have any issues with the length of that wire in my car. The part that was loose on my ash tray was the cigarette lighter itself. After I retightened the lighter, it has been fine. Getting to the lighter is somewhat tricky. Popping the wood trim out from around the console is easy, as is removing the ashtry assembly from the wood trim. I'd love to know how they assemble these things because when I took mine apart two springs that came flying out (like one of those fake jars of peanuts with the springs in them. LOL) never would go back in properly--it's not the end of the world, the ashtray door doesn't spring open like it's supposed to, but it doesn't bother me since I have my sat radio mounted right there. Once you start taking everything apart it's pretty self explanitory. ;) Quote Link to comment Share on other sites More sharing options...

Lexus Owners Club Posted April 26, 2021 Share Posted April 26, 2021 Unfortunately, the system won't function without the control panel. Best idea would be to find a secondhand panel and it should then start working fine Quote Link to comment Share on other sites More sharing options...
