Air volume at the dash vents...

[jazzman_q]

I noticed that when turning the fan up, I can hear the fan motor increase in speed, however I’m not feeling the increase in air coming from the vents.

I have made sure the vent roller was in the open position, and all of the buttons for the dash, upper, and lower vents were lit. I cycled through each individual vent while also changing the speed.

I thought i had read, that the ignition switch could be a culprit, but I have already replaced it. I’m not sure if its the resistor, because as i said previously, I can hear the motor change speed.

So the easy question is:

What’s next?


Thanks in advance.
