Vent panels.

The 'vent panels' on the BX...what do they actually do. I know this may seem stupid question to some but I really don't know?[:I]
Also the black filter mesh behind the 'vent panel' has broken down/dissappeared on one side. Any suggestions as to what to replace it with.
Still haven't had chance to carry out very extensive service on it either, got boxes full of parts from Gsf and even treated it to 'Magnatec' oil but this weather is stopping me doing anything. Frustrating!![:(!]

Vent panels? don't they ....vent? I remeber years back when the BX was a new model that you could get a sort of clear plastic cover instead of the vent panel. This made the pillar see through from inside the car. I believe it came from Citroen dealers.

Yes. True. but what would they be venting?!? Yeah, know the things your on about {I think} but thought they were mounted above the vent, which was still present? They gave an extra window along side of BX...pehaps making it easier to reverse park!!!!

The vent panels are there to let the compressed air out when you close a door or tailgate. Otherwise we would all be blowing back windows out! The mesh on mine has gone west so I'm considering using aluminium mesh.

The vents extract air from the cabin very effectively when on the move. Try temporarily blocking them up, and note the difference in flow from the dashboard 'blower' nozzles when the actual blower is turned off.

I think the plastic quarter covers were dependant on the model as opposed to being an option, but I could be wrong. Incidentally they both fell out of an old Bx my dad owned and had to be bonded back on by a windscreen fitter.
Most modern cars have hidden vents, usually in the boot exiting behind the rear bumper.

Yeah, think your right. Think it was only the upmarket ealier models {pre '88?} such as 16TRS but not sports models like GTI, GT and Sport. Well thats cleared up that little mystery!! Noticed them on Volvo 240 estates also but those are much smaller. Im hoping {prob in vain, that all this crappy weather means long, hot summer!!!}

Well our window-falling-out model was indeed a 16 TRS!!
Thinking about it, the black mesh stuff bears a striking resemblance to the sort of stuff used in pond filters. Have you actually tried main dealer? They might be able to point you in the right direction if they can't help themselves.

The BX 16TRS had dark brown perspex windows fitted to the rear quarter posts (C-posts) as standard. I didn't think they did anything - except disintigrate after about 10 years.

Pond filter mesh? Good thinking!! Yeah, very similar material....can't do any harm and think theres some knocking round in 'Garage full of crap'.

As Dave says the vents are there to let compressed air out of the car (there is actualy a basic valve in place to keep outside air from comming into the car through them (its like a rubber cat flap)). Interestingly the tigra they didnt put one in and they had to alter the electric windows so that the passenger side window comes down by about 1cm when any door is shut other whise you cant shut the doors because of the preasure on the in side of the car...

Like the old Vauxhall Velox (late 50's model) - if you slammed the door, the front windscreen popped out!

Maybe it was a solution to what happens with CXs - apparently the rear quarterlights are prone to being blown out!

how about the oldfashioned name for the vents,it was once a big hype-through flow ventilation.
