Almost certainly blower motor. You may be able to save it with some lubrication o the fan bearing. You can access it through the cabin air filter to try that. Under the plastic cowling, passenger side, under the hood. Lots of people try WD40, but I'd suggest something with greater penetrating and lubricating properties.
On my recently acquired '03, there were so many leaves and pine needles in there, they turned to concrete-like mud in the drain. The seal around the cabin air filter also fails, allowing water into the blower motor, which kills it... you can clean off the factory seal and use a bead of RTV or silicone to reseal the housing to the firewall.
If you have to replace the blower motor, it's not such a bad job, about a 3/10 difficulty. I just put a used blower motor in today. Now I have air flow, but no cold, so I have an additional A/C issue to track down. Among other things!
