I have cleanded the cabin AC filter its damn easy to do.
i went to this AC wala and he was asking 500 to clean the AC filter.
Its easy in 2006 (new Shape)
1. Press the glove compartment from both sides and it will come out.
2. behind it there is a white plastic box
3. open the clips, inside the AC filter resides.
4. Take it out and go to a pump and get it AIRED and its done.
its sinthetic fible filter. am not sure to put a alu gause ot pt guase.
I was shocked to see that there were alot of dead mosquitos and flies in the plastic bot please clean that as well.
do not wash the filter as it will start giving bad smell
i usually clean the filter once a month its good for the AC Cooling.
NExt time i clean will take pics and post them here . (AC DIY)
