1997 E300 Windscreen Air Vents Blocked?

[doonie]

Hi,

The air vents in my 1997 E300 estate have become very 'weak' recently, making front windscreen demaist very slow. Generally, all the vents, side, centre and rear, are very weak now and I think there must be a blockage.

I have no idea where to start to unblock the system (clean a filter?), but am willing to give it a go if it is a relatively simple job, and I can get some advice from this forum.

Any advice greatly appreciated!!!

Could be that your internal cabin filter is blocked . This is usually located under the glove box area. You should find a panel in this area which can be removed with a phillips head screw driver. remove the filter and use a high pressure air compressor to blow the dust out . Blow the air from the cabin side of the filter otherwise you will be forcing the pollutants deeper into the filter. You can always wash it but you will have to wait for it to dry.
