2006 Chevy cobalt
I have a 06 Chevy cobalt and the HVAC fan speed
switch isn't working. What are the steps I should
take to get that working again.
YOU HAVE A BLOWER MOTOR RESISTOR GONE BAD. IT IS LOCATED UNDER THE GLOVE BOX WHERE THE BLOWER MOTOR IS LOCATED. THE RESISTOR CONTROLS THE FAN SPEEDS.
I've replaced the resistor this morning still not blowing any heat but I can feel heat coming from my vents.
YOU MIGHT HAVE TO CHECK THE BLEND DOORS THAT CONTROLS HEAT FOR LEGS , FEET, DEFROST, THEY ARE CONTROLLED BY BLEND DOOR MOTORS.
How would you go about checking that?
The blend door and its motor do not affect blower fan operation. If your blower is not working check fuses, then have a look at the blower itself. If the blower is working on all its speeds then see what the blend door is doing. You might have to do some you tube searching to find the exact location of those parts, but they're under the dash on the passenger side.
