my beater A/C vents won't stay in position, and flop around pretty much at whim. Today while at the hardware store I noticed some wave spring washers in the metric section and grabbed a bag of the 6mm set. Since these are springy they help to increase the preload on the nipple that holds the vent in place, but since they are also really thin they don't move the nipple away from the hole like a larger washer would do. Total cost was about $.70 I think.
