Hello,

Before I sound like a complete idiot, I bought my 2008 acura tl less than a week ago. I have noticed that my center a/c vents barely blow any air out compared to the one to the left of my steering wheel. I can't seem to find any way to increase the airflow on the center vents. Is there something wrong or am I just missing something since I'm still not 100% familiar with the vehicle? It's an Acura certified pre-owned and I can't imagine they'd overlook a problem like that. Can anyone help?

Thanks,

 

Just got a new 04 - 06 Acura Service manual. In the heater control section it says check your cabin filter if you noticed diminished air flow in the cabin... GL

 

I noticed the same issue with my '05 a couple years ago and had the dealer check it out during a service visit. They checked all the vents and couldn't find any problems. The service advisor told me "That's just the way it is."

 

How easy is it to replace the cabin filter?

 

This was one of my first questions on AZ. I thought it was a little odd that the center vents weren't pushing out much air, no matter how high the fan speed. I never had it checked out (too lazy I guess), but when summer came around and the need for the AC arised, things were a lot different. The center vents performed as I originally expected. Not sure what is behind the reason, but I'm sure that what you are experiencing is normal.

 

Depends on how brave, handy, or rich you are. If you're brave, you drop the glove box and the under-dash baffling and pull the lower part of the passenger side dash (tan) free from the upper part (black). You'll see the filter in the duct system on the firewall. There are pictured threads in Problems & Fixes that will show you how to do it.

If you're handy, there are pictured threads that will show you how to cut an oblong hole in the skirt of the tan piece so that you can deal with the filter just by dropping the glove box.

If you're rich, let the dealer do it and write a good-sized check.

This process vies with the lack of a trunk keyhole and the incredible way you proceed to change turn signal bulbs for the "What Were They Thinking?" award for 3G TLs. Changing HID bulbs is a treat, too, but you only have to do that about every 100,000 miles.

 

I have found it to be the foam tape in the duct work behind the radio and info center. It has deteriorated causing a significant gap for air to escape behind the radio causing the center air vents to blow weak. Tape up the gap with some aluminimum-mastic duct tape and should be good as new.

please post some instruction. I have this same problem. The center vent is weak and my entire radio/aluminum trim feel very cold to the touch

This will give you the instructions on how to pull your car apart then it's just taping up the gaps with the aluminum HVAC tape that you would use on your house duct work.

 

I am wondering if this is the issue in my '05 now. I noticed today that my driver side center dash vent doesn't blow anything unless the rear vents and the door side vent are closed. The passenger side center dash vent blows plenty of air no matter if the other vents are open.

- Blower on High
- Manual setting to force via dash vents only
- Rear vents closed
- door side vents open - great airflow
- passenger dash center vent - good airflow
- driver dash center vent - little to no airflow

So now to figuring out how challenging it is to get behind the radio and controls to take a peek at the foam gasket condition. I have never taken any of my dash or center console apart in this car. Time to RTFM I guess.

 

I'm sure it could use a cabin air filter anyway... But it's probably leaking into the dash. That, or a combination of both...
