Does anyone know whether or not the A/C controls from a 2011 (12, 13, etc) Sienna Limited would be plug and play in a 2011 Sienna LE? I'm mostly interested in the AUTO feature, but not sure if I need any additional parts to make it work properly...for instance, the GPS radio for display purposes or any other sensors.

Thanks in advance for your help!

I have a hard time believing that it is as easy as replacing the HVAC control unit. For one thing, the Sienna Limited HVAC control ties into the 3.5 inch display at center top of the dashboard which shows which mode the HVAC is in. Does your LE do that. I would guess that this change would require sensors, one or more ECU"s and some wiring changes. And what about the HVAC control for the rear passengers? Aren't the ones on the LE and Limited different?

This is what I'm trying to determine. Like you, I imagine there's got to be some other hardware necessary to run this. However, I did find some Limited vans with the standard head unit that have the AUTO A/C controls. In fact, the van from which I'd be buying these controls have the standard stereo unit in our LE as well.

Here's one example - http://image.motortrend.com/f/photo...llery/43597302/2013-toyota-sienna-se-dash.jpg

I haven't looked, but I assume the harness that plugs into the A/C is the same regardless of trim level, and that it's merely one or more of those wires attaching to another piece of hardware on the other end (or a different ECU) as you mentioned.

As far as the rear controls, they are also different.

It looks like the following P/N is also necessary to make it work:
TEMPERATURE CONTROL MODULE OEM PART #88650-08150 622186

Still doing some more research...

I'm looking forward to more replies on this as I, too, am looking to do this mod. Thanks in advance!!
