    Re: 03 SLS Cabin Air Filter

    Do a search under member mikekilpatrick. I addressed this scenario when I did mine, it is a pretty difficult process. There are THREE rectangular filters that stack up in that tiny space to make ONE filter! The easiest way to get to them is to remove the C clamp on the gas pedal, put the pedal out of the way, remove the seat and then start taking the filters out one at a time. Problem is, the last one sometimes gets stuck, if this happens and you can't get it out with a clothes hanger, you will have to drop the passenger side glove compartment and remove the blower motor (about a 20 minute job) and then fish out that last filter through that access point.

    I have all of the details in my post.

    My tip would be to spend the $85 and enjoy a nice cup of coffee and a doughnut in the waiting area whilst the Caddy technician changes them.

    Took it out while bleeding to death a year and a half ago. Left it out and no regrets.

    Both Dadillac and Mike's procedures will work.. The more stuff out of the way, the easier it is. I replaced mine ONCE with the seat, the gas pedal and the tranny cable in place. Not easy... It would be an interesting race to see if it is less time to remove the gas pedal and the front seat then it is to fight in the tight spaces...

    Passenger Compartment Air Filter Replacement

    Removal Procedure
    1.gif
    1. Remove the left sound insulator panel. Refer to Closeout/Insulator Panel Replacement - Left in Instrument Panel, Gauges and Console.
    2. Twist the shift cable grommet and position the cable grommet away from the filter access cover. It may be necessary to cut the tie strap, and to slice and peel back the foam insulation in order to position the shift cable grommet out of the way, in order to access the filters.

      2.gif

      3.gif
    3. Remove the filter access cover (1). Push the cover down, then pull the cover out.

      4.gif
    4. Remove the tape on the first filter.
    5. Remove the first filter by pulling the filter tab.
    6. Remove the tape on the second filter.
    7. Remove the second filter by pulling the filter tab.
    8. Remove the third filter by pulling the filter tab.
    Installation Procedure

    Important
    Lubricate the new filter guides with a spray silicon for ease in installation. Keep the filters as straight as possible during installation.



    5.gif

    1. Install the first filter into the HVAC module assembly.
    2. Use the tab or a long screwdriver in order to raise the filter, so that the leading edge of the filter catches on the holding rib inside the filter case.
    3. Install the second filter in the tab of the first filter.
    4. Slide the second filter into the remaining channels of the first filter.
    5. Raise the filters, so that the leading edge of the second filter catches on the holding rib inside the filter case.
    6. Install the third filter in the tab of the second filter.
    7. Slide the third filter into the remaining channels of the second filter.
    8. Fold the second filter tab down and pull the third filter tab up over the second filter.

      6.gif
    9. Install the filter access cover (1).

      7.gif
    10. Reposition the shift cable grommet. If the insulation was peeled back, secure the foam back into the original position.
    11. Install the left sound insulator panel. Refer to Closeout/Insulator Panel Replacement - Left in Instrument Panel, Gauges and Console

    Aside from silicone spray on the interlocking parts, I would suggest a midget contortionist with the patience of a saint.

    Re: 03 SLS Cabin Air Filter

    Hey, is the wix filter the same as the ACDELCO filter?

    I mean, same install, no issues, same amount of filters, right.


    wix part number 24874

    And also, is it me, or is acdelco on crack asking that much for filters.


    Edit: this is for a 98 SLS

    The AC Delco filter is a charcoal filter, the Wix is not. They will both filter out dirt and debris. Only the AC Delco will filter out odors, due to the charcoal. I think that Fram makes a charcoal filter for our cars, but I have been unable to locate one.

    Wix is the one I used from http://www.rockauto.com. Basically the same at the original except as Don mentioned.

    Re: 03 SLS Cabin Air Filter

    That's up to you. I bought the Wix because I didn't want to pay the high price for a Delco. Then I bought the Delco to replace the Wix because I couldn't stand not having a charcoal filter. I will stick with a charcoal filter.

    Re: 03 SLS Cabin Air Filter

    I would add that my car smells better and the A/C works better without ANY filter.

    If you look at how it is put together it is clearly a last minute engineering kludge. Instead of being at the "head end" of the air flow (like it is in the Deville and new STS, etc) they put it at the end. It seems to be in the perfect spot to hold dirt and moisture against the A/C system were it kinda gets funky.

    With out the filter the evaporator seems to stay dryer and smell a lot better.
