Couple of basics you need to check and let me know what you find. First, when was the last time you replaced the cabin air filter? A dirty cabin filter will reduce the air flow coming from the vents. If that is ok, when you feel the air diminish, press on the recirculation button and see what happens with the air flow with it in recirculation and when you have fresh air come in. Does it change? If it does, clear out your glove box. Too much stuff like papers, napkins, or tissue paper can be sucked up by the recirculation door. Here is an example. Turn on a regular fan and feel the air flow, next get a piece of paper and put it in back of the fan. You will notice the paper is being pulled in by the vacuum but because of that obstruction, your air flow diminishes. Same concept here with the recircultion door and that sits behinde the glove box. Sometimes it takes a while before the air diminishes because it is gradually pulling in the paper until it gets to the recirculation door vent. Let me know what you find?
