You can "rewire" the vacuum plumbing so that the center vents are open all the time. It's really nice to have heat for your right hand as well as your left. All you have to do is to remove the glove box so you can get at the vacuum manifold, then remove the center pod line from the manifold (I forget the number -- it's in one of Sixto's threads) and tee it into the main vacuum line. The center pod then gets vacuum any time the engine is running and is thus open at all times.
