Low Airflow

Low Airflow
I have an '04 V70 with ECC unit. I noticed that when I turn it on everything works fine but after about 15 minutes the airflow will diminish tremedously throught the vents. I can hear the blower blowing like a hurricane but hardly any air coming out. This happens with the auto button on or off. It will be fine once I turned off the car and turn in back on. Could this be a bad blower resistor?

Non Volvo-specific answer. But, if the fan is running, the resistor is probably o.k. Especially if you can manually vary the speed of the fan. More likely, its
the gizmo (vacuum) that adjusts the "doors" that direct the airflow. Loose/cracked hose is suspect number one. Airflow on most cars is mechanically directed via vacuum control.
Caveat: I've never been under the dash of our Volvo to look or seen the elusive shop manual for our '06 to learn how these work.
Chrysler Sebrings have an endemic resistor problem which let us run the fan on high or none at all. Replaced it, and now its variable speed again. That's what leads me to conclude its not your resistor.

I've forgot about this problem until yesterday when I drove for more than 30 min. in the heat. So how do I check the vacuum for the damper? It does sounds like the hose is blocked off after 30 min. because I can still hear airflow but very little coming out of the vents and dash. But like I said it would be fine after I shut it off for 10 min. and then airflow will diminish after 30 min. of driving. Tech, have you got any thoughts on this?

It sounds very familiar to my problem and culprit was a bad evap temp sensor. Where is this sensor located?

Where is V70 Cabin Filter Location??
Hello,
I thought I read somewhere online that the filter was located under the cover of the glove box. I took off the 2 torx screws, and removed the cover, but didn't see any area that would accomodate the filter (it is quite large!)
Any idea on where to look and how to install it?
Thanks!
