Hi all I just thought I would put a couple of pics of how to clean these relief vents which go in the pillar, they are usually covered in a brown grime, and the little rubbers are out of shape. they are not hard to do, and the plastic part of the vents when separated can go in the dishwasher...along with the air vents from the dash, this did not hurt them and saved a lot of cleaning (note I did not put the little rubber pieces in) if the rubbers are not flat, they need to have something heavy sat on them for a few hours to flatten them out...

When you pull them apart all the little nipples break off, and unless you have a poly welder, you need to glue with 2pk epoxy (arildite)





I just used a toothbrush and dishwashing detergent.
