Default Is There a way to Slow Down the Blower Fan

We recently purchased a 2007 Rx350 and just returned from a 2500 mile road trip. This is the most comfortable car I've ever driven. I did notice however, that the blower fan seems like it needs to slow down one or two more steps. Even in 'LO' I was constantly adjusting the vents to keep the wind off of me. Is this normal? If so, is there a 'fix' or mod I can do to slow the fan down a bit?

Were you adjusting the temp or fan. It looks to me you were adjusting the temp if you seen "LO"

Fan speed controls on my RX are LO, M & HI with a setting in between each of those. Adjusting the temp displays the new set temp.

I was adjusting the fan speed. I should add that it has the Navigation system and the climate controls are included in that on screen system although the individual temp controls for driver and passenger is a switch with an up or down arrow just like the models without Nav

Try making sure the rear air vents are open. Other than that I don't know.

I was hoping maybe it was a common problem and that someone had come up with a mod to slow the fan down. Maybe adding a resistor to the fan motor. It would no doubt slow the fan down at all speeds, but I'd be willing to give up some air flow at the high end to have less at the low end.

Are you looking at the " LO " on the temp page or the fan speed page?

On the nav page you can adjust where the air flows to. Like windshield, AC vents or towards your feet.

Put your Climate on AUTO. Then adjust the temp up and down. If you still have too much air. Check the vents to see if there any closed.

I run mine with the passenger side window vent and back seat vent closed. To get more flow to the driver.

You can adjust the vents themselves (between 'full open' and 'shut' ) so as to control how much air comes through each one.

Did you set it to "fresh air" instead of "recirculate" ?

kickin8, It was set on fresh air. My wife has the car on a short business trip the rest of this week, when she gets back, I'll try the recirculate mode.
pauljcl, That may be the answer right there!

Thanks guys!

The fan speed doesnt change if your in fresh air or recirculate.
