Ambient air temperature sensor

[Lumina2008]

Hello every body
I hope one to help me to find the location of ambient air temperature sensor and the cabinet temperature sensor as a/c is not working sometimes and other times it work properly and many technicians examin a/c system and found nothing wrong in the system so I think it may be a temperature sensor issue...

The cabin air temp sensor is in behind the dash panels on the drivers side.

Might be able to get to it from under the steering column or with cluster out. I’m a bit foggy on that from when I did it.

The sensor for the evaporator is also down there and there’s a mod to pull it out a little to get a better reading.

The ambient temp sensor is from right behind the bumper. So bumper off to access it. In where the radiator is.
