Hi All,
I THINK I know the CAUSE, the PROBLEM and I am going to try what I THINK is the CURE.
Please follow this post to the end and see if you agree with my diagnosis.
CAUSE: CABIN AIR PRESSURE
Here are 3 examples of what I have noticed that basically stops the AIR FLOW out of the FRONT AIR VENTS:
1. If you REMOTE START the vehicle with the air conditioning turned ON, the inside of the vehicle becomes pressurized.
As soon as you open the door, the air pressure in the cabin is released, thus putting pressure on the BLEND DOOR ACTUATOR to keep the FRONT AIR DISTRIBUTOR VALVES held in place, which appears to be the function of the BLEND DOOR ACTUATOR.
I don't think it has anything to do with the REMOTE START, I think it has do with CABIN AIR PRESSURE and the BLEND DOOR ACTUATOR (Please keep reading).
2. You are in the vehicle, ALL WINDOWS CLOSED, and a door is opened. You then lose air flow from the front vents, even though you can hear the blower going full blast.
3. You are in the vehicle, ALL WINDOWS CLOSED, you open a window. You then lose air flow from the front vents even though you can hear the blower going full blast.
PROBLEM: WEAK BLEND DOOR ACTUATOR
CURE: REPLACE THE BLEND DOOR ACTUATOR - I THINK!!!
I talked with another Outlook owner, who I know personally, and he had the same problem. He took the vehicle into a dealer, had the BLEND DOOR ACTUATOR replaced and the problem was resolved.
So, I am going to get a new BLEND DOOR ACTUATOR, replace it (hopefully in next few days), and see if that resolves the issue.
I will get back to you with my results as soon as I replace the BLEND DOOR ACTUATOR.
ANOTHER POTENTIAL FACTOR: REAR BLOWER
The Outlook is a very well sealed vehicle, and, between the FRONT BLOWER and the REAR BLOWER, there is a LOT of AIR PRESSURE in the vehicle thus creating a HIGH DEMAND on the BLEND DOOR ACTUATOR to keep the FRONT AIR DISTRIBUTOR VALVES in place to divert air flow to the UPPER AIR VENTS on the dash.
This is an ASSUMPTION on my part, but I think it is a factor.
PLEASE GIVE ME YOUR THOUGHTS.
I see that there is a new GM CUSTOMER SERVICE rep (William R. (assisting Kelly & Jessica) who is monitoring the site.
Hope to hear from Kelly, Jessica or William R. also.
This is my first post and I hope it is helpful and resolves this issue.
Look forward to your comments, thoughts, suggestions, etc.
Thanks to all.
George
