Under the passenger side wiper on the firewall. Is this a cabin filter? I did a search, and I thought f bodies didnt have cabin filters. ANyhow it looks nasty and the filter needs replaced. I just dont know what it is for? Its a 1996 Z28.

 

There was no "cabin" filter on a 96 F-Body.

 

You can see it in the picture. It is on the left side behind the fan wires.

 

I've looked at my original picture and don't see and don't know what you are referring to.

If you are talking about that box sitting there, that's the PCM-not a filter. http://shbox.com/1/fw1.jpg

 

OH, i feel dumb. Thats what it is. It looked like it had a filter inside it.

 

I believe there is a little vent in the casing.
