I have an automatic AC/heater system. This problem is unfortunately intermittent. It is a problem with both air condition and heating. The blower motor works and the fan speed increases correctly when a higher temperature for heat or a lower temperature for air condition is selected. The air condition compressor also feels correctly cold when engaged. The issue is I feel only room temperature and I don't think the cold in case of air condition or the heat in case of heating is getting to me. Again that is not always the case. Turning of and on the engine a couple times can sometimes fix the problem. When it then works I hear a plop as if a door opens. Any idea where I should focus my attention?
Do you

Ok it sounds like I would look at the blend door or blend door motor. Here is a pic of both they are both available at you local parts stores once you know which is bad, I would suspect the blend door motor.

Thank you. Where are those parts located? Also do you still think it is those parts when I observed it to happen more often when there is a difference in temperature between the outside and inside. Outside is cold but inside is warm due to sun.

Ok there will be no trouble code with this kind of problem. Now as for the location I will include a pic. I suspect the pop you hear is the motor when you are in there look for anything that fell in the vent and is stuck in door it could be something that simple otherwise the blend door motor would be my suspision without being there to check myself. If you need me to clear anything up for you ask ok.

So sorry I just found your response. It is behind the glove box area, you may have to remove the glove box but that should be it. If you more just let me know.
