2014 Tahoe A/C Blinking, even on hot days. Sensor Location?

[MDelgado]

   Hey guys, so the last hot day of the summer and my A/C won't come on. The snowflake just blinks.... Apparently, this feature is to protect the compressor on below freezing days. So I order the A/C ambient temperature sensor. Not to be confused with the ambient temp sensor for the outside temp on your dash. Problem is, I can't find it.... Anyone know where this sensor is? It has to be outside the engine bay, like the other Dash temp sensor, but no luck. I figured it would be in front of the rad like the other sensor?? If you guys could help me out before april comes

Answering my own question from last year to help others.  There is no separate ambient sensor like the pickups have.  The sensor used for the dash temp reading is dual purposed.  Anyway, my snowflake was blinking because the charge was low.  I had a leak.  Only way to find that out was with a HVAC scan tool
