96 Blazer Possible Vacuum Leak?
I was replacing the heater core and I have noticed prior to doing this that I could hear what sounded like a vacuum leak under the dash. Since I had the entire dash taken apart I decided to start the vehicle in order to locate where the noise was coming from. To the best of my knowledge it is coming from directly behind the controls. If I turn the control to floor and dash the noise is eliminated I have taken a picture of the back of the controls. There is one tube that does not have a vacuum line running into it. I am curious if this should be the case. Also, I am looking for any additional guidance or advice on how to determine whether or not everything is operating properly.

The other port is a vent. Should not leak vacumn after it vents after switching control positions.

It is only a vent to release vacum pressure to the actuators. No on under hood port.

I have attached a video where you can hear the vacuum in the background. There are two settings in which the vacuum doesn't leak. |

video is not all that good for me to observe with my computer. 68 meg file and very short with a odd sized screen format. |
