Blower motor strength

Hello Everyone - I have a 2009 Tundra Limited Crew and when I crank the blower up to max it just doesn't seem to blow out air as heavy as I feel like it should. I particularly notice this when running recirculated max A/C. I realize its a huge cab but the air strength/speed coming out of the vents under the max setting seems lower than it should be. Is this normal for the Tundra's or I am just expecting more than the blower motor is capable of doing. The airflow in the rear vents feels like it is just barely coming out. I do not have a frame of reference for other Tundra's as this is the first I have owned. Thanks!

 

Have you checked your cabin air filter? Awhile back I thought my blower was getting pretty weak and I was ready to order a new one. I pulled the cabin filter and it was absolutely clogged with crap. Threw a new one in there and currently enjoying a good, strong, cold, airflow in our 114 degree temps.

Life is good again...

 

Funny you mention that. I just put a new one in like 2 weeks ago. Well let me rephrase. I have a K&N cabin air filter that I cleaned and recharged and put back in. I had pulled it and put the OEM style in until I got the cleaner solution for the K&N and there was no difference in air flow that I remember. I am going to swap a paper one back in and see if its different though. Thanks!

 

This isn't 100% the issue... but if you don't have any clogs in your vents, your blower motor might be on its way out. Mine is doing the same thing. It sometimes never fully gets up to speed and other times it blows full force and then starts slowing down. I've been researching this and seems to be a fairly easy swap for a new one. One piece of plastic molding to remove and then three bolts holding the motor and disconnecting the electrical connection

 

When you run the AC in recirculation mode (MAX), you will notice diminishing blowing performance as the evaporator freezes. Switch it to allow outside air in and this problem goes away. More noticeable in areas of humidity. Make sure the drain isn't clogged too.

 

Thanks Bgkahuna11325 I will give this a try. it is very humid here in MO currently. I will also check that drain.

 

I just changed my blower motor out ($130 autozone) and this took maybe 20 minutes tops to change out.... if that. Pretty sure it took longer to get my tools out and then put back up versus the time actually working. My a/c blows hard now, just like a hooker would for the last line of coke.
