Was driving down the road and suddenly my AC blowers stop completely. No hot air or cool air blowing.
Any ideas what it could be?
It's happened about 5 times in the past but would start working again all of a sudden. Now complete stopped
 
Need to check for proper power and ground at motor when is turned on. If not there then likely a relay or connection problem. If is there then you have a failing motor.
 
I have the same problem on my 2005

what if the blower suddenly stopped working while running errands and now won't turn back on?
I have changed the blower motor and the resistor and or relay. and it still won't turn on ? i am leading towards cluster
