Do the 2005 TB's have a cabin filter. Some posts were vague. Just seems to have not a strong airflow no matter the vent setting. Thanx in advance

Playsinsnow said:Can you feel an increase in airflow at each fan speed increment? I noticed mine wasn't and replaced the blower motor resistor module that is under the glove box.
Search trailvoy.con for the air filter install mod. Don't feel it's necessary for me.
RayVoy said:You don't have cabin filters in the '05; however, you could have something plugging the air ducts.
I would pull the blower and inspect the box, maybe something has turned your truck into a home.
If everything seems clear, connect the motor to 12v and see if the motor spins fast and free.
RayVoy said:My '05 Envoy tossed a ton of air out of the vents, the floor or the defrost when the motor was on high, you must have something restricting the flow. There is a mode door, that lets the driver select windshield, vents, floor; maybe it's stuck. The motor that operates it is called an actuator.
Can you select each of the modes and can you feel the air flow change from one to the other?
When the motor was changed, was it wired correctly? Could it possibly be turning in the wrong direction, could the resistors be wired so that it never gets full voltage.
Do you have the manual selection system, or the auto system with the interior temp selection? I have noticed the air flow of the manual systems seems to flow higher than the auto systems.
Unless you have an 02, or a select 03, that section will be sealed up. You have to cut it open yourself. No screw will be there, but the post for it should be.GMCRick said:I watched that video, and my 06 Trailblazer EXT doesn't have a screw where the cover is. I don't see any way to open it. It looks like it is sealed up. Not sure why mine looks different than the one in the video.
Only a couple years had them. You're right though, it's sealed up with no access door. However, there's a guy here that makes the access doors on his 3D printer and sells them. Then once you buy that, a screw, and some filters, you can cut out where the access door would be and his part sides right in. It's a copy of the OEM ones.GMCRick said:I watched that video, and my 06 Trailblazer EXT doesn't have a screw where the cover is. I don't see any way to open it. It looks like it is sealed up.
