A/C Heater controls not working

[mdntblu]

I have a 2016 EL Limited. Recently my wife has been saying that every so often the A/C Heater controls won't work. I've driven it many times and never experienced this. Has anyone else ever had this problem?

Can you offer more info as to what it isn't doing?

I'm trying to figure out how to upload a video actually. It's a video my wife took this morning.

I noticed the system was in AUTO mode, with the set temperature at "LO". I also noticed the outside temp was 63. I couldn't tell if the "Auto" button on the controls was illuminated. So, I suggest turning off the AUTO mode and then turn the fan up manually. I'm thinking the system is saying "Hey...its already about as low as I can make it, so I don't need to do anything".

Another option would be to set the auto temp to HI. As long as the engine is hot, it should start blowing pretty quickly.

Kind of hilarious that you actually said that. I wrote that exact same thing to my wife a few hours ago when she was sending me video.

But after that she said it's not on Auto and only thing that is working is the rear A/C.

I just noticed something else....the passenger side shows "Dual", but at some point in the video the knob for the passenger temp doesn't have the yellow light illuminated. Thats wonky.

EDIT: Just checked mine. Outside temp here is 65, set at LO Auto and the fan started blasting. Ignore my comment about the Dual indicators. When the display box is blue, that indicates Dual Mode is selected. When its white, it means it is not in Dual mode.

Looks like you've got an issue.

Yeah that is weird. So I'm guessing the computer is messed up. UGH.

When you set temp to LO that’s basically a wide open throttle signal to the HVAC system, no matter the temp at that setting it should be blasting AC.

Plus as soon as you change the fan speed it will go out of auto so yeah something is messed up. Sounds like a trip to the dealer is in order. Hold onto that video because sure enough as soon as you get there everything will be working fine

Yeah and it's not. ARGH. Might have to take it in.

Yeah I know. My wife said when they were on the freeway for about 20 mins it started working but smelled like hair dryer air at first.
