Question about 2004 GMC Canyon
The blower motor works on speed 4 when the dial is set on 4. However, on speeds 1,2,3 the blower works intermitently. The motor woks on speed 4 any time, so I don't think the motor or control is a problem. Could it possibly be a loose ground somewhere???
Thanks for any help ...
Check the blower resistor pack - usually located in the heater air ducting in the blower fan airflow. Check for loose connections and open circuit resistors on the unit.
If speed 4 works always, its unlikely to be the blower motor ground connection.
