Hi all,

I'm a new member here but have owned Grand Prix GTPs for the last 8 years and love them! I recently learned that like many new cars my 2005 Grand Prix GTP has a Cabin Air filter that should be periodically replaced to keep the cabin air clean AND to allow the environmental system to run efficiently.

I would like to replace mine, but can't find the exact location of the filter or the procedure to replace the filter anywhere after countless hours of searching on the net and searching around the car. I don't want to just randomly unscrew things trying to locate it.

I'd greatly appreciate it if someone could send me the procedure with illustrations or copy and send me the appropriate pages from a service manual if you have one.

Thanks very much in advance!

Greg
