Air Conditioning Blower Fan Failing

I have had the air conditioning system on non stop lately. Recently, I started hearing a sound coming from the passenger footwell and then the A/C would stop blowing. I would turn the A/C off for 10 minutes and then back on. The fan would blow for a while but then would start to stutter and eventually die. I can repeat this indefinitely. Seems to be heat related to me (something getting hot then cooling off, only to overheat again). Could this be a relay? Or maybe the blower?
 
Try removeing the blower and rinsing it down with hot water to remove all the dust and crap. This is what I did to mine and it worked great. But first thing first, check all fuses and relays. If that's good move on to blower and also check the sensor going to the side of the blower aswell.
