Are there 2 ambient temp sensors for 2012 suburban?
 

I'm getting the blinking 3 times AC light. A lot I've read says that it's the ambient air temp sensor saying it's too cold.
My dash air temp reads fine. I took off the one in front grille and my dash temp went away, I out it back and I get the dash temp again.
So There's either two temp sensors or the the blinking light is a different thing.
I saw somewhere else there there is a second ambient air temp sensor. I can't find it if there is one.

Does anyone know if there are two? and where the one that controls the AC located?

No. There is only one ambient temp sensor. Typically, if your A/C light blinks, the system is low on freon.

Yesh.. The freon was low. Lets hope it's just a small leak.....
