How to Replace Buick Cabin Air Filter

The cabin air filter is used to filter the outside air before it comes into the cabin from the vents in your air conditioning and heating system. It keeps out more than dirt; it also filters out pollen and pollutants that can cause breathing problems. It is recommended that you change the filter every 20,000 miles, or if you start to notice a musty odor. In some cases, you may need to change it more regularly depending upon where you live. Dusty roads clog it up faster than paved roads.

Use your owner’s manual to determine whether or not you have a cabin filter on your Buick. The filter goes by many names: dust filter, pollen filter, HVAC filter, HEPA filter or air conditioning filter. Make a note in your owner’s manual of the date and mileage when you change the filter.

Instructions

  1. Open your glove box and remove the contents.
  2. Slide the pin off the limiting stop arm on the glove box and remove it.
  3. Grab hold of the back and the front of the glove box and squeeze them towards each other. This will pop the side clamps free. Drop it down in order to see the cabin air filter faceplate.
  4. Slide open the faceplate by lifting the latches on the sides.
  5. Pull out the old filter while keeping all the dirt on the filter and not in your Buick. Make note of the arrow directions.
  6. Clean out the filter area with a hand vacuum, and then wipe down the sides with a damp cloth. Make sure that the gaskets and seals are in good condition. Change them if they are worn or cracked.
  7. Place the new filter in the channel with the arrows in the right direction.
  8. Put the faceplate back on, and put the latches back in place.
  9. Re-install the glove box.
  10. Put the limiting stop back in place.
  11. Place all contents back into the glove box.

Cabin air filters are an inexpensive way to keep the air quality in the cabin at its highest levels, and it may take some of the stress off your fan by removing any obstacles. Since they are inexpensive, you might as well stock up on several of them; they never expire, and you will always have a clean one handy.
