My A/C blowing hot air?

I submitted a question earlier and got an answer. Thank you. I just wanted to add to my question and wasn’t sure how to do so. My question is.
The mode door is the door I need to move the lever on? Right?
This is exactly what’s occurring. I forgot to include this. I’m not sure if it will make a difference or not but better safe than sorry. When I turn my AC on it blows hot hot heater air. Not room temperature air “hot” heater air. So I turned AC & Heater both completely off and it’s still blowing hot hot heater air out of the vents even when everything is turned off. So obviously it’s stuck on heater mode? Correct? Wouldn’t you say that was the problem? This is what’s making it so unbearable to drive. Because even with the windows down I can’t even enjoy the breeze due to the constant hot heater air blowing out of my vents at me even though everything is turned off. I never knew there where so many doors. Is it called the blend door or mode door? I just want to make sure I’ve got the correct door and can for the time being go in and manually move the lever(arm) that controls the AC/Heater door from off heater to on AC? Just until I can afford to replacement the motor for it and install it. I’ve seen other people on YouTube just manually move the lever for the time beginning and just wanted to make sure that’s something I will be able to do as well? I’m sorry please bare with me. I’m learning and just want to avoid any mistakes if possibly. I’ve been researching this for 2 months now. I’m 98% sure this is my problem. I just didn’t have a clue which one of the many doors I needed to move the lever on and where that door was located under my dash? Thank you for helping me and being so patient with my questions. I love the fact I can ask mechanic questions regarding my vehicle and get correct quality advice and answers so quickly. I truly appreciate it.

Sincerely,

Okay! So the one in the diagram is the correct door I need to find and manually move the lever? Because I know there are multiple doors.

Do I remove the glove box and then I will be able to access it the blend door?

Recently the a/c on my Altima started blowing warmer and warmer. Having worked on vehicles over the years, I did the typical checks. A/C clutch was not engaging, freon was charged. So, I replaced my compressor as well as my expansion valve. After doing this, I vacuumed the system then put freon in. The clutch is engaging on the new compressor. But I still get only hot air. I checked the fuses, couldn't find a problem there. The only thing I haven't checked is my a/c relay and Nissan is very vague on their diagrams of where the relay may be. I'm frustrated with this and open to suggestions.

Compressor control valve. My 2013 Altima has been blowing hot while still. Would start to drive then it would cool down. This went on for about a year. Now it was just blowing hot all the time. I changed the control valve and now it works like new. It's easy to get to - from under the car on the right side. It's held in by a snap ring. Just be sure to have a/c system drained before you remove it! I bought the part on eBay for about $40.00 because no one around here stocks it. Hope that helps someone!

I have a problem on my Nissan Altima 2014, whenever I turn on the car the AC is on full blast. I can change the temp and it works on all locations. But it just won’t move to lower blast, I’ve tried turning off the battery to see if it would reset it but it didn’t do anything.

I have recharged it but it stills blows hot air. I do not what to do. I'm a PFC in the army so I don't really get paid well enough to have a mechanic fix it.
