Alright, if the blower motor's not working on your 2007 Santa Fe, there’s a handful of usual suspects to check.
First thing I’d do is check the blower fuse and relay. They’re in the fuse box under the dash and sometimes under the hood, depending on trim. If those are good, move on to the blower motor resistor (especially if it failed gradually, like losing low speeds first, then all of 'em). Those resistors tend to burn out.
Now if the motor’s not running at all (no matter what fan speed you set) it could be the blower motor itself. Easy way to test it: unplug it, run 12V straight to it with a jumper, and see if it spins. If it doesn’t move, it's toast. If it does, then your issue's further up the line — maybe the switch, the resistor, or a ground problem.
Also worth mentioning, Hyundais from that era had occasional issues with melted plugs or loose connections at the blower resistor or motor, so check those connectors for heat damage.
Luckily, the manual has all the wiring diagrams, test procedures, and step-by-step instructions for removing the blower motor if you need to swap it. So grabbing one would be a good start 😉
