• Q: How to replace the cabin air filter on 2003 Buick Park Avenue?

  A: Before accessing the passenger compartment air filter the left sound insulator panel must be removed first followed by pushing down and pulling out the filter access cover. Unroll the tape from the first filter before extracting it with the filter tab and then remove tape from the second filter for extraction in the same manner. You should also perform this filter replacement technique on the third component. The filter guides require application of spray silicon lubricant during installation so the filters can be managed efficiently while keeping them straight. The installation method begins with inserting the first filter into the HVAC module assembly while using either a tab or long screwdriver to lift it until the leading edge secures within the filter case holding ribs. After placing the second filter into the tab of the first one you should insert it through all remaining channels. Your second rise of the filters should aim to establish leading edge contact with the holding rib inside the filter case. The last filter gets placed within the tab of the second filter before it is slid through all remaining channels. Put the second filter tab below the second filter by folding it down while raising the third filter tab above the second. After that, install the filter access cover with both sound insulator panels.
