So i got home a little bit ago and i press the button to bring my windows up. My passenger window goes up fine yet my drivers window is stuck all the way down 
then i shut off my car and try to start it back up. But all i get is a single *click* But my stereo, headlights, instrument cluster, etc. all worked. And my battery is a newer optima which has never been drained. My car has always fired right up. No hesistation from the starter, nothing. Until now. I tried cleaning the battery terminals, cause that's all i can really do at this hour. But i have a feeling it is the starter solenoid then? A
Any help is appreciated cause this is the first time i have encountered a problem like this.
Thanks.
