There is a test, I don't recall what it is but it involves pushing some buttons on the ACC panel. I can tell you that if yours didn't run under those conditions there is a problem. You can find the plug for the motor under the little cover up front on the right side and try and jumper 12V to the motor directly and test it that way...I'd bet the motor is DOA - it was on mine.

Replacement is easy and intuitive. You can buy just the motor side with fan and don't have to buy the entire assembly with the "slave" fan and frame (I know that slave isn't the PC term but that is what it is called). That will save you some money. I recommend replacing the belt too though if you go that route.
