my friend has a 2008 vibe and everything was working fine, until one day the a/c and heater fan from inside the car stop working, anybody have any suggestions?
Does the fan work when you turn it all the way up (top speed)? If so you're looking for a Heater Blower Motor Resistor. It's installed next to the blower motor it self.
If it doesn't work at any speed check the fuse box to see if the fuse for the blower motor is blown. If that is fine it sounds like you're going to need a blower motor.
