What a horrible location Buick picked to put the interior air filter. I
went through the extra effort of removing the lower dash trim on the
right & left sides of the dash. The driver side didn't have to come off
after all but I found out after the fact that removal was not necessary.
The filter is located between the firewall & Air box, inline with the
center hump in the floor. You have to have the hands of a contortionist
to get your hand above and to the right of the gas pedal. Flip a panel
down then another one up and then pull a tab to pull the filter out.
I found out my blower motor is under the dash on the passenger side.
Lots of spaghetti under there, wires running all over the place. I
removed the lower right side of the dash trim just to look under there.
Both left & right lower dash trim pieces have three things that have to
be removed from them in order to remove them out of the car, A air temp
sensor twists out, a wire harness has to be unclipped and a second wire
harness for the footwell lights have to be unplugged as well.
The owners manual doesn't explain filter removal procedures, but says to
contact a GM dealer about replacement. It does say if you do remove it,
it don't need to be reinstalled. You can leave it out but then the air
coming in won't be filtered.
About 6 tiny oval leaves and a bamboo twig fell on the rug when I pulled
the filter out. Part of the filter frame broke trying to get it back in.
You really got to spring it to make the bend into the hole and clear the
gas pedal. The frame is plastic and is notched out so it can be bent
back & forth.
An airhose cleaned the filter out good. Mine is 3 inches high by about
10 inches long. You can almost see though it, its so thin.
The Owners manual says to inspect the filter at 15,000 miles & replace
every 30,000. Ha ha ha ! Not after what I went through today. I don't
know what these fiters cost, but I've heard some vehicles filters were
up around $30.00
I may eventually leave the interior air filter out altogether. Afterall
I'm old school & all my previous cars didn't have one and 25 years of
non filtered air didn't seem to be a problem for me back then or the
millions of other folks driving GM cars.
A Goodwrench friend changed the original Gas Filter today, it took about
two minutes to R & R the filter. Mine has the easy squeeze plastic clip
on one end. It took longer to jack the car up & set the jackstand in
place than it did to R & R the filter.
At 60,000 I'll change the gas filter myself.
