Same thing happened to my car. The blower motor and the resistor had to be replaced. It cost me . The dealer actually had the parts in stock because it happened frequently enough with the Echo that he wanted the parts on hand. If it is your problem, you may be lucky enough to find a rebuilt blower motor.
The blower motor resistor is defective.
Check connections at the blower motor, blower motor resistor and at the switch. You may find a melted connection.
neither,blower resistor or blower module controls fan speeds.
Check the fuses first and the blower relay.
If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.
Start with: Possible control, blend door or blend door actuator, low pressure switch, leak in system.
Bearing in motor seizing Try removing motor and drilling small hole in end to lubricate--sometimes this works
I would suspect the blower motor speed resister is shot.
I would look into the blower motor resistor module
Probably a bad blower motor resistor
Defective Blower Motor Resistor Pack.
No, that would have no bearing on the blower motor. Check the fuse, blower motor resistro pack, and the blower motor itself.
