2007 Suzuki SX4 Question: Blower suddenly stops

Ive have seen this many times, the blower motor could be on its way out, but for now you give it the "fonz" tap on the blower or close to it on the heater box works just about everytime for me!

In some vehicles, running the blower motor on low all the time burns out the blower fan switch. It may be due to incorrect gauge of wire in the switch. I always run the blower on 3/4 to full speed or completely off if possible on any vehicle. Most people will turn the fan to low if they get to warm with the heater, or to cold when they run the air conditioning. I think it puts a strain on the wiring and the motors when they are ran at low speed. The best thing to do, in my opinion, is to run the motor at 1/2 to full speed and adjust the temperature setting to where you are comfortable. I would like a professional's thoughts on that opinion though.
