The vertical louvers of the A/C vents are not made of strong plastic and easily break, typically at the fulcrum points.
The following illustration shows a typical louver while the red arrow indicates the pin that has a tendency to break.
The A/C louvers are lubricated at the time of manufacture with fine grade lubricant oil. With use and due to continuous A/C usage the lubricant dries up and makes the louvers tight to move. If you apply too much pressure trying to free the jammed up louver you will end up with a broken louver pin and the whole vent would need replacement. It is very expensive, more so in the Highline version which has chrome lined A/C vents. According to the SA the center A/C vent assembly costs upwards of Rs 7000/-. The solution –
The solution is simple. Apply a good quality fine grade lubricant (standard machine oil used in sewing machines would serve the purpose) on all the fulcrum points of the A/C vent at a regular interval – I suggest a lubrication routine once every 2 months if you use you A/C always.
In my case I had all the vertical louver pins broken on both the right and left vent (the ones besides the door). When I heard about the cost, I thought of applying typical Indian “Jugad” method – which I picked up from one of the threads here from someone who had fixed his Palio vents this way – rebuild the damaged part using M-Seal. I rebuild all the broken pins using M-Seal, once dried; I filed them to shape using a set of jeweler’s file. Then applied a thin coat of Araldite over the rebuild pins. Once the Araldite dried up I fitted them back with a layer of white grease applied generously. Now the louvers move smoothly and as a matter of fact feels smoother than the original. VW's stand -
VW is unwilling to replace the louvers under warranty - they claim that these are damaged by the user. But unfortunately do not mention the need for regular lubrication in the service manual.
There is a filter underneath the glove box. The filter material is exposed and you can feel it with your fingers. |
Thank you, Anirban for clarifying the filter issue.
Excellent workaround DIY for the broken vents.
IMO, the vents on both the doors sides are more flimsy than those on the centre dash, hence they get damaged easily. This is a case of use of cheap plastics as only cheap form of plastics tend to get brittle and easily break when exposed to lower (or extreme) temperatures.
Using petroleum Jelly instead of white grease will definitely prolong the life of your modufication as Petroleum Jelly is lighter, less dense in consistency, more viscous, less acidic, ph neutral, and will not solidify as much as white grease when cold.
I also installed an Ioniser in the cigarette lighter socket and a moisture absorber (DampTrap) under the drivers seat to keep cabin air fresh, odor free and damp proof. Also, did a small DIY for a automatic wireless led light in the the glove box. Works wonderfully well.
Cheers.
