Well, I am at a loss as to why my heater fan doesn't work so I think I remove the fan switch and probe around with my multimeter.

How do I remove the fan speed switch?

 

The whole panel is held up with plastic tabs on both top and bottom. You need to remove the side panels...last time I did it I had a lot removed because I was fixing a heater core leak, so I don't know exactly what is the minimum of parts removed.
