Dash Panel Vent Removal

I just bought a 2001 and looks like a soda has gotten into the vent direction controls. I would like to remove these and clean them. What is the best way to remove? Does the entire dash have to come out? Thanks

Are you talking about the vent knobs that turns the heat up and down, fan etc ?

If so they just pull off.

I'm talking about where the air comes out of the dash. The fins that move up & down and side to side are sticky until they heat up from the hot air while using the heater. Thanks

Ok I see, try this thread......

Hope that helps.

Thanks. The Alero should be the same...right?
