resistor pack troubleshooting.
My blower works only on the 2 highest speeds. I pulled the pack, expecting to see a "pack" of resistors, but, what I see is a resistor and, well, a pack of springs.
I am curious about how this device works. Does it have some way of measuring the airflow past it?
Is there a way of troubleshooting beyond just cleaning it and it's connections?
