SOURCE: Blower AC fan not working.
Hope you have both fixed your problem by now; my system has been down.
In most auto applications, the bearings of small fans and motors are made of sintered phosphor bronze with graphite or petroleum lubricant embedded in it.
Since there isn't much load on these, the bearings can outlast the rest of the car but they do have a tendency to get gummy and since the fan motor doesn't have much torque, it may have trouble overcoming the stickiness and start turning.
If it wasn't for the buried location of most blowers, it would be a simple job to flush out the bearings with a penetrating lubricant such as WD-40 that is mostly volatile and doesn't leave much residue behind to complicate (gum up) things again.
This problem is common to some computer cooling fans too although many of the small CPU cooling fans actually have PLASTIC bearings!
Including some that were clearly marked as 'ball bearings.'

try checking if the turn off valve needs adjusting stick your head under the hood and get someone to turn the heat setting on and off you can see the valve moving

Your AC is low on refrigerant; The AC compressor needs a minimum amount of regrigerant to run. If and when it does run (while low on refrigerant) the air coming out of the vents will not be cold. The refrigerant you require is R-134A and is available over the counter but if you are the least bit unsure as to how to add refrigerant, taking it to a garage that does AC recharging would be your best play. If you want to try to add refrigerant on your own you will need the following, 1LB can of R-134A, an AC hose adapter to deliver the refrigerant, and preferably an AC pressure guage to ensure you are not overfilling the AC line which will damage the system.
