Hi,
With the moderate weather we've been having, I've been running my AC fan at maximum speed (without running the AC unit) and noticed a rather annoying problem. One of my AC vent on the dashboard would not stay open very long. I'd turn it open and after a few seconds, up to a minute or two, it'd close itself, as if has trouble staying open. However if I run the AC unit, the colder air apparently keep it open, so I'm wondering if there's something keeping the vent doors open that is not working correctly at normal temperature (60's, 70's)? Has anyone had this problem?

 

I've seen this on at least one car. I get the impression that the friction required to hold the vent doors open is insufficent and with higher blower speeds, the air actually closes the vent. Ask your dealer to replace the vent assembly.

 

Make sure you have all the vents open. If you close too many of them, then others will pop closed.

Yeah, I did have the other vents closed, because I'm always the only one in the car, and from past experience with other cars, closing the others help to blow more air through the remaining vents (and cool me off faster ). The other poster is correct in that there doesn't seem to be enough friction for the particular vent to stay open at full speed. In any case, I've discovered that the vent will stay open if I use fan speed that is one step below the full fan speed.

Thanks!

 

Just noticed the same with my clubbie
When I close one or more of the vents, then the center-left one will close itself with or without the A/C on...
