First check the fuse/relays on the electric panel, second check connections maybe something is loose, third maybe the blower motor resistor has to be replaced (common issue) Check in ebay for parts and last the motor maybe is damaged (need replace the whole unit) good luck

Does it fan run on its highest setting only? If yes, it's the thermosistor the fan motor plugs into. Easy and cheap part to fix, usually by going through the glove box.

Yes mine would randomly work a little too. Found out it's the blower motor. Need to replace it. Haven't yet though lol

Hyundai was suppose to call me back with it but never did so I'm not sure. Probably not cheap. Cheapest part I found was like 50 dollars so I'll probably just buy one and I think I know someone who can put it in

Behind the glove box is the 2nd air filter of the sonata cars. (1st being in the engine compartment). take off the glove box and pull the small filter out, make sure to have some kind of vacuum as there may be a lot of rubbish. mine had a lot of leaves and random debris from the out side. as soon as i pulled filter out and clean out rubbish a/c worked again. the reason being is that the 2nd small air filter behind the glove box will block the entire air flow so nothing will come out of the vents if the filters clogged up. Also the blower motor is literally right under that filter so if its the motor that you can access it right there.
