Now that warm weather is here, I've been running the A/C at top speed a few times lately in my new-to-me 04 EX-L. I've never had a Honda before, but it doesn't seem like the highest 2 speed settings on the A/C blower fan are any different from the 2nd-from-highest setting. Basically the airflow from the ducts and the volume/pitch don't change at all on the top 3 speed settings. Is that an indication that my blower resistor needs to be replaced? Or is the speed difference of the top 3 settings so imperceptible that I'm just fooled into thinking it's the same? The airflow coming out of the vents on the highest blower setting doesn't feel nearly as strong as most other cars I've ridden in. I put a Fram Fresh Breeze cabin filter in there last month when I bought the Pilot, because the original one was pretty cruddy. Perhaps the filter is reducing the flow too much? I even pulled the blower motor out of the housing and ran it through the different speeds while holding it in my hand (carefully!) and still couldn't see, feel, or hear a difference between the top 3 speeds.
