After turning the unit on, it clicks to start, but then clicks right back off...

I just installed a used Whirlpool ACQ122XK airconditioner, that has been stored for about a year. Anyways, I turned the unit on before I inserted it into its housing unit and it worked just fine. Then I inserted it into the housing unit and ran it for about 10 minutes and it ran fine, but the front radiator looking piece was sort of grimy, so I turned it off and vacuumed it, even though the bottom of it was sort of wet. I did not bend any of the aluminum pieces or anything, but now it won't turn on. When I turn the unit on, the lights come on and it sounds like it is going to start blowing, but then it clicks, behind the "power square" with the on/off switch and the cool/fan speeds, and the blower turns back off. Then about 30 seconds-1 minute, it clicks again, like if the blower is going to come back on, but then it clicks again and turns off. I have tried to unplug it and let it set for 3-5 minutes and try it again, but it does the same thing over. Do I need a new unit or is this a minor problem that can be fixed? Or even a solution, that I can possibly try, that might make it work? Thank you for any help that I can get!!!
