My problem is that I have little pressure blowing out of my vents. The temperature is still good (cold and hot), however it is barley blowing out, on both recirculated and fresh air settings. I thought I read somewhere how to fix it, but after much searching, I could not find it.

The weather forecast is calling for 95+ degrees by Friday, so hopefully I can fix it ASAP.

From what I've read before, my problem is at the "flap" that chooses between recirculated and fresh air. Does anyone have any experience in fixing this?

Thanks in advanced guys

 

Can you hear the blower changing speeds when you turn it up and down? If yes, then your issue is likely your blend door(s). If you switch to defrost or floor, does it blow out at a decent rate?

 

^^^ He hit it on the head.

Either blend doors or the resistor block on the fan motor or fan motor itself.

 

Thanks for the responses guys. I just checked and yes, the fan changes speeds like it should. However, output overall seems to be about half of what it should be on both recirculated and fresh settings.

Today is my only day off this week so I'm going to try and get it fixed before the AZ heat really starts. Is there a DIY or any previous threads on how to access the blend doors? I thought I read somewhere before that I can manually shut the doors so I have at least one setting that has good pressure.

What do you guys suggest?
