Air conditioning control panel

[Richard-W]

I have a 2014 IS300h with 70,000 miles and a fault on the air con control panel on start up. There is power to the panel as airbag and seat belt lights come on, but the air con controls take about 20 seconds or 200 yards driving for the full display to come on so adjustments can be made and then works fine. I had the system re-gassed last service.

Has anyone else experienced the same problem?

I have a 2014 and on startup yes theres lots of input lag on the temp controls. I just put it down to the systems powering up.

I had this problem. On maintenance they got codes for servomotor failure for some of the servos ie. the air con system stucks on boot and resets itself after about 30s or so. The problem went away on itsself after some months and now the air con works and starts immediately when I start the car. Could be some software bug (or sign of 12V Battery going old/bad?) also since my air condition have been working perfectly during all this time. Changing the servo is very expensive since lots of disassembling is needed in mk3 IS. I think in earlier models it was much easier to do.

Thanks for the replies, it appears to be a fairly common and minor issue. There was a different minor fault on the unit a few months ago that went away on its own, I will wait and see if it gets worse.
