My 2011 ES350 has 43,000 miles and runs great. I took it to Firestone today for tire rotation, full synthetic oil change and I let the guy talk me into adding fuel injector cleaning.

When I got the car back, I noticed the Auto Climate Control button wasn't working properly. If I press it on, I can't press it off. The green light stays on. If I turn off the fan, the Auto button goes off. I am positive the button worked before the service.

Any idea what could have happened that would cause this? I know the service guy had to press some buttons to turn off the "oil change required" message. Could he have messed something up in the process?

Thanks.

 

Not quire sure I understand you, but here goes:

1. Auto button - pressing it once turns on the system in Auto mode with green light.
2. Pressing Auto again will not turn off the Auto light.
3. Changing any fan or vent position setting will turn off the Auto mode. For instance, changing the fan speed manually will turn off the Auto light. Or - changing the system so that it's venting in your face instead of at your feet will turn off the Auto light.
