Hello and welcome to JustAnswer,
The panel that's located below the steering column has a small couple of slits cut into the panel in the right side. That's where the in car temp sensor is. Could you check for me if the electrical connector or if the tube is connected to the panel?

Here is a picture to help you out.

Yes. It appears that it's connected. I did another diagnostic (pressing the auto recirculate buttons) and it added code 22 which is the "Compressor Lock Sensor Circuit". Is there a way to reset this? Where is it located?

Did you get my reply? Yes it's connected. Now I'm getting error 22 - compressor lock sensor circuit. is the sensor inside the compressor?
Expert:  Victor replied 1 year ago.
Yes the lock out circuit is built into the compressor. You could have a bad sensor or a bad compressor. Do you own a volt/ohm meter? If you do, I can send over some testing instructions.

Yes. My dad is an electrician so I'm pretty good with a meter

Ok, follow these diagnostic steps and let me know what you find.
