How do I fix my fresh air blower?

I Spilled coffee on my climate control unit, then the air blower stopped working immediately. Checked fuses. None blown. Took apart climate control unit and cleaned all the buttons and contacts because they were sticky and wouldn't move. I did not notice any dried liquid on the circuit board itself, just the buttons. All the controls on the climate unit work flawlessly. The fan speed indicator bars just go up then down without the blower turning on. I can hear the ac turn on. I can feel heat from the vents after a while, just no air flow at all. I have never had any problems with the air blower at all before this occurance.
