Guys, I have a 91 accord that once in a while, the interior fans will not switch on. I notice this on the hot days when I need my A/C. 8/10 times, once I turn the fan knob, the fans start blowing but there are also days when nothing happens. Today, it failed again...I just left the fan switch on position 3 and after 10 minutes of driving, they started blowing again. Any idea what's causing this?

TIA

 

sounds like the blower motor is bad if you went under the glove box and banged on it the motor will start back up again...
