Try disconnecting the plug on the A/C compressor then turn the A/C on in the car.... No Cold air is gonna come out but it will trick the car into thinking the A/C is on and kick the fans on constantly... Your compressor probably burnt out, But i dont know why the fans wouldnt turn on regardless... Just leave the fan speed low so you dont have outside air blowing in your face.... Did you get any electronics wet while washing your car????
