Yesterday, the blower motor on my 2007 Honda Accord was set on the highest speed and it started slowly slowing down and then stopped working althogether. When I left to go home from work, it seemed to be working fine. This morning I went out and started the car to get the ice off of the windows and it worked fine. By the time I got to work, the motor slowed down and then shut off again. I just went to lunch and it was running fine again. Is the motor possibly going bad? Or is it just the restistor that needs looked at? I don't have a ton of money to fix it and the weather is pretty snowy and cold at the moment. Thank you!

 

Replace resistor

 

Could be the resistor and motor. They both wear in time
