A/C Not Working
Out for a drive with the misses and hot as h*** so I push the AC button and only flashing and nothing else but HOT air....Read through some previous threads and it seems I have the dreaded B0333 code. So, I looked for the OTS and not sure where it is. Is it down near the bottom of the radiator shroud on the passenger side or under the car on the passenger side. I will try and put a shot of refrigerant in Monday but for now my FEARS are growing and I'll be out BIG BUCKS.....

Also, it seems to blow hot air out the vents all the time.

The OAT probe is on the passenger side, down low sticking through the right side of the radiator shroud. A little pointy thing with a tab in a slot, held by a plastic push pin from inside the engine compartment. There is a blue connector inside the engine compartment at the probe.
With the hood open, start at the under hood light, follow the under hood light wire down along side the engine side of the radiator shroud. At the under hood light connector along side the shroud, the OAT probe is about a foot further down, where you will see the back side of the OAT probe and top of the push pin that holds it in place.
Looks pretty easy to change.
