    2000 SLS Cabin air filter?

    Just a quick question, there is no mention of a cabin air filter in the factory service manual for my 2000 SLS.

    But they sell several different ones on rockauto.

    My question is simple. Does the 2000 SLS have a cabin air filter or not? If so, I would like to replace it while my dash carrier is sitting neatly on my garage floor.

    Thanks in advance.

    Remember - that filter is in three interlocking pieces - you pull the first tab, pull the first part, drop the remaining pieces, pull the tab, and repeat. Installation is the reverse. Carefully vacuum the filter cavity if it has never been changed.

    With the HVAC stack on the garage floor - piece of cake. In the car, maddening frustration.

    Unless you always park under trees, leave it out. Pop the little access door back in place and let it go at that.

    If you want to replace, I highly suggest the A/C Delco filter as the frame enclosing the three pieces is more substantial. It is not a fun replacement and make certain to use some silicon lube on the interlocking pieces when you install! The Fram filter I once used had a flimsy frame and was even more difficult to install that the Delcos I have used since.

    They do seem to help in the spring and fall pollen is extreme in some parts of the country.

    I changed my cabin filter out a few moths ago and it was a real pain. Make sure to get a quality filter a the cheaper ones tend to come apart where the filter media is attached to the plastic frame. The location requires you to have to bend the filter to get it in place. I went through 3 filters that came apart before I got tired of trying it and took it to the dealer to have them put it in. They initially quoted me $85.00 for an hour labor to install it. 2 1/2 hours later they finished. Fortunatly they kept to the $85.00 quote...

    I just replaced mine while the dash was out. I ordered a fram baking soda cabin filter for it off ebay. It's suppose to obsorb odor. With everything out it's really easy.

    Re: 2000 SLS Cabin air filter?

    Older post I know, but thought I'd throw my two cents in and confirm some of these other posts. Yes it is a pain in the rear end, as I found out having changed mine out from a couple years ago with a WIX 24874 and it went smooth surprisingly. After a lot of dusty driving, I decided to replace it again this year with the FRAM CF8391A carbon and baking soda filter. Pulled the WIX out and it was actually pretty dirty with a lot of junk in the opening. Went to install the FRAM filter and got the first piece in. Lifted it up to get the next section in and it only went in about 7/8 of the way and it got stuck. Pulled that section out and went to pull the first piece out to check it and removed only the plastic from the box. The cheap glue had let go and the element was still inside the box. Not even going to describe how much fun that was to fish out. Due to the nature of how they need to curve to go in, I'm guessing the element popped out of the frame inside the box. After much cursing, I blew out the WIX and reinstalled it with no problems seeing as how the element is actually attached to the frame. Listen to the people on here and get an AC Delco or something reputable with good quality. With as much of a bear as it is to install, you don't want something that's gonna come apart on it's way in. Also with both of the filters assembled out of the car, the FRAM filter's flow arrow is backwards I believe. The WIX arrow points towards the rear of the car and the FRAM filter points towards the front. I don't have the original to compare flow direction. Just putting this in here in case someone else goes searching for this thread.

    Re: 2000 SLS Cabin air filter?

    I replaced the cabin filter in my 2002 STS several months ago. Often the cabin filter has never been changed previously, so you probably will be trying to remove old units that are stuck together either because of age and/or dirt. But, the good news is that when the old ones are removed, the hard part of the job is done. I would go ahead and replace the filters because the position of the blower motor will allow all of the dirt to fall into the motor without the filters; but that's your choice.

    A previous suggestion was to lube the edges of the plastic of the new ones before you insert them; but before you do that, smooth the plastic edges of the filters with sandpaper or lightly with a dremel to remove any burrs, etc. Then they'll go in much easier. Installing new filters that are properly prepared is not difficult; its removing the old ones that's usually a PIA.

    Why GM decided to locate the cabin filter (which should be changed regularly) is a mystery to me, but maybe someone can provide a logical reason for the location (other than to test the car owner's patience and dexterity).

    Re: 2000 SLS Cabin air filter?

    ............. or, the flip side of the question: "Why is there a cabin air filter in the first place ?"

    As long as the cowl intake grille and screen is in good condition, that will prevent large chunks from getting in - as in any other car. I took the PITA filter out in 12/05 and never put in a new one. A couple of years ago I used a fiber optic borescope to look at the evaporator core fins and filter area - clean. (On the other hand, if you park outside, under trees ...............)
