Most likely its the blower motor unless it has a relay that you cant check you just have to replace it. sometimes you will have a few relays that are the same and you can use one just to see if thats the problem,but make sure its not one that controls anything major.
You have a problem with Blower resistor module, which is an electronic device with a large heatsink at the back. You can get it from Mopar shop or you may repair yours. REpair instructions can be obtained by emailing me the part number of your module to: [email protected], we arrabge a once off $10 paypal payment and I'll send you detailed instructions and diagrams how to to that.

How would you know if it is the resistor module ($12 on ebay) or fan? Mine works in 3 and above but will not turn on, on 1 or 2.
I found this:

Sounds like low speed coil in the Blower Fan resistor block has failed. The Blower Fan Resistor Block is usually located in the air ducting adjacent to the Blower Fan. The Resistor Block consists of 3 or 4 coils of special resistance wire attached to terminals which connect to the wiring that comes from the fan switch and then to the Blower Fan. The block is on the output side of the fan unit so that the airflow from the fan past the coils inside the duct assists in preventing them from overheating and burning out.
Access to the Resistor Block is from under the dash. To replace, remove the multi-pin connector and then undo the screws holding in the block. Check air duct for leaves and dirt which may have caused the coils to fail. .Replacement is the reverse procedure

It is the blower motor resistor. Look under the passanger side dash and locate the fan housing (looks round and black in color. Then locate the resistor it will be in that housing usually withtwo ten millimeter nuts or two simple screws holding it in. unplug the harness to the resistor and remove the resistor. Part store price is approx. 50.00. Note: on aftermarket (not Jeep) resistor sometimes you have to modify the housing a little to get it in. Hope this helps.

it is likely that the elements the selves have burnt out under the seat cover they can be replaced but you have to remove the seat covers and gat parts from a dealer

Run a new wire to the motor from the switch this will do 2 things for you. It will tell you if your switch is still good, and if it works you just fixed your problem.

Check your fuse thats a new vehicle so you might want to let the dealer look at it if its not a fuse. It should still have dealer warranty
