Weird AC behaviour

[ScousePaul]

I noticed that my A/C on the 430 wasn't blowing cold recently when we had that warm spell. The A/C was regassed just a couple of months ago by Lexus when I had it serviced - not sure if they test functionality at that time or not. 

Was going to get them to have a look, but then had a weird experience today where the A/C selection was just greyed out on the LCD screen. Couldn't enable or disable it and the temperature controls didn't function. After a short while though they sprung back into life. Still no cold air, but certainly something odd going on. Anyone come across anything similar? Suggestions for what to check before I get it looked at?

Sorry Paul cannot offer any advise - let's hope it's not th the common corroded ac pipe lines.

yeah I wish I hadn't read that thread recently... I'm going to stay optimistic though until I know otherwise! :)

The MFD, multi functional display ie the touch screen on these cars can fail. 

Could it be the display has failed and the AC is perfect?

Search on this site for remedies.

The screen did work - just that the A/C on/off icon was greyed out. All other controls worked (though I couldn't change temperature). The odd thing was that a little while later they sprung back into life. Sill not blowing cold though, so back to the original issue... Have found a few threads on A/C not working - some simple regassing (though this was done in service very recenty), some a bit more involved (corroded pipes as Mark mentioned).

May take it round to local Kwik Fit to start with. Always found them honest and cheap on these types of checks/fixes. Summer is looming! (though it's bloody freezing today...)

If you love your car, Take it to a proper garage, I wouldn't trust places like Kwik fit or Halfords

Agreed, I don't think they have the knowledge to cope with such a complex car.

Paul, have a chat with Paul Frost at Lexusspares direct. There is not much he does not know about LS 430's. His no is 07590 072646 Cheers, Roger
