I’m having this problem with my 1998 2.5 liter TJ where my air will not blow out of any vents. Never had to deal with something like this so I don’t know what is going on. This is a video of what’s happening. It seems like it is recognizing that I’m turning on the air but it won’t actually turn on. It makes a really weird noise which you can hear in the video when I turn it off. Can it be the blowers or maybe a fuse?
Put the video up again. Let’s see if it works. But no it doesn’t sound like anything is running but my Jeep idles at a little bit higher rpm when ever I turned it on which means it recognizes that I’m trying to turn it on I believe

I think what you're hearing is the blend door changing positions. It is powered by the vacuum system so it may lead to a small spike in RPM when used.

I would check the HVAC fuses, then the blower motor resistor, the switches, and then the blower motor itself

If all but the highest fan speed is bad it's usually the resistor
