Dear 50 Traveler/Justin, I have the exact same problem. Someone wrote about it on the p-15-d24 forum, and said to replace the rubber seal through Robert's. The two flanges on either side of the cowl vent are attached to armatures that must be adjusted and tightened to mimick each side, that is to say to become symetrical in function. Another thing, if you tighten the play in the handle to cowl armature to much you can monk up the stop at the bracket, that is to say bend it where it enters the pivot, so be ever so careful and gentle in your adjustments. Mine is off (Cowl)at the body shop to match paint for a Sunvisor I bought so I have the priveledge of readjusting mine again as I re-install it. It is best to remove the Radio when working on all that under the dash, but go slow, leave the beer on the workbench you really can't drink it upside down. Tom
