MB 2008 C300 cabin air filter where

2008 - 2012 models should have the access panel behind the glove box if the van is equipped with a filter. Not all models have a filter.
You drop the glove box down by disconnecting the support straps.

I have a 2008 Grand Caravan and it states that the cabin air filter is behind the glove compartment, so like you I remove the glove box and nothing. I called the dealer and was told that on some models even though they say there is a cabin air filter in actuallity there is none

Good luck,

Marty

If you have an SXT model, it probably does not have a cabin filter. To get to the potential location, empty the lower glove box. Push each side of glove box inward to allow the tab on each side to clear the dash bottom cowling. Each tab looks like a Shrek ear. When the glove box drops down and you don't see a flat plate as per the drawing on the previous post, but you do see what looks like the black interior of a salad spinner and above that a full width black plastic piece that curves to the front of the vehicle, there is no place for the air cabin filter.
A cabin filter on a Dodge Caravan would not be located under the hood below where the wiper blades are!

The cabin air filter is usually located behind the glove box or at the base of the windshield in the cowl area over the HVAC inlet duct. The exact location can be found in the vehicle owner’s manual or a filter reference guide at the auto part store where you purchase the cabin air filter from.
On most Fords, the filter is located under the hood in the cowl area. On Chrysler models, it is located under the dash. On GM products, it might be under the hood (Impala, Lumina and Monte Carlo), under the dash (Avalanche, Silverado, Suburban and Tahoe) or behind the glove box (Venture). On Toyota, Lexus, Nissan and most Honda models, you’ll find the filter behind the glove box. There is no cabin air filter even listed for a 1998 Oldsmobile Regency.

On vehicles where the cabin air filter is mounted under the cowl at the base of the windshield, some disassembly may be required to replace the filter. This may involve removing a plastic cowl cover. The area around the filter usually collects debris, so this area should be cleaned to remove any leaves, bugs or other debris before the old filter is pulled out. This will prevent any contaminants from falling into the HVAC inlet duct.

On vehicles where the filter is located behind the glove box, the glove box may have to be removed to replace the filter. On others, the filter can be accessed from under the dash and pulled out of a slot in the HVAC unit.

Most cabin air filters are flat-panel filters, but some have unusual shapes, so they will fit the HVAC inlet duct. Some filters also come in two sections to make replacement easier.

The cabin air filter is located behind lower (larger) glove box.

Open the glove box, detach lever (right side). After unhooking both sides of the box (press towards inside) it will come out.
The filter element easily comes out (as drawer).

Slide in the new element, put back the glove box and attach the lever.

Hope this helps.

It will either be behind your glove box, or will be located under your hood by the firewall.

Behind the Glove Compartment
1. Open the glove compartment and remove all the items from inside of it.
   
2. Remove the glove compartment assembly retainer screws with a Phillips head screwdriver. Refer to the repair manual for your specific year and model series BMW for the exact location of the screws or carefully look around the perimeter of the interior glove box assembly to locate the screws.
   
3. Locate the lower trim panel retaining screws behind the glove box assembly. Remove the screws with a Phillips head screwdriver and then remove the panel.
   
4. Remove the foot-well air duct.
   
5. Loosen the retaining screws of the control module box to all you to lower it down.
   
6. Turn the cabin air filter panel retaining knob counterclockwise to open the panel. Pull the filter removal tab outward to remove the filter.
   
7. Use a shop vac to clean out any noticeable debris from the cabin air filter housing interior.
   
8. Insert the new filter and reverse the order to reassemble the foot-well air duct, the trim panel and the glove compartment assembly.
   
Under the Hood
9. Open the hood and locate the cabin air filter housing. The housing is located near the cowling on the top section of the firewall. Some models place the housing in the middle of the cowling, on both sides--left and right--of the cowling or on the passenger side cowling. Removal of the cowling and placing the windshield wipers in the upward position may also be required on certain models. Some 7-Series BMWs place the filter housings on both the left and right side undercarriage of the hood.
   
10. Release the cabin air filter duct clamp. This can either be released by unclipping the air filter duct by pressing a retaining lock with your fingers or using a flathead screwdriver to pry off a retaining rod.
    
11. Lift the cover upward--or downward on hood-installed 7-Series BMWs--to reveal the cabin air filter.
    
12. Remove the cabin air filter from the air duct. Vacuum the air duct with a shop vac.
    
13. Insert the new cabin air filter(s) and reassemble.
    

This solution pertains to a 2008 Honda Pilot...To replace the cabin air filter which is located on the passenger side of the vehicle behind the glove box: Open glove box and remove stored items...while sitting in the passenger seat, pull towards you on each of the two clips on the left and right side of the glove box...this will cause them to become loose and the glove box will tip out completely exposing the inside of the dashboard. (Alternately...carefully pull towards you on the top center of the glove box which will cause the left and right side stops to pull away from the edges and allow the glove box to tip out) Here it gets tricky...the box holding the cartridge for the cabin air filter is the large black box on the left side behind the glove box The filter fits in a removable tray vertically inside that box. A pressure clip at the top of the box allows the vertical cover to be removed exposing the tray with the Cabin air filter... BUT!!! There is a plastic bar an inch or so high which has been placed there by the manufacturer to prevent most from changing the filter without the service department being involved. This bar must be cut with a sharp sheetrock knife or hacksaw and discarded, (it will not be reinstalled). Then there is a flat metal bar behind the plastic bar that can be removed using an 8mm socket and a phillips screwdriver. There are 2 8mm screws and one phillips head screw on each side that must be removed in order to remove the metal bar. THEN you can remove the cover to the cabin air filter box, pull out the tray with the filter (note how the filter is in the box so the new one can be placed the same way) reinsert the tray with the new filter and replace the tray cover. All other steps to finish the job are obvious as everything is the reverse. Actually the whole process is a lot of trouble and unless you are determined to change the filter I would recommend not doing it.

Remove the three torx screws using a torx-20 screwdriver...pull back the padding in the footwell...there is tab holding the left part of the plastic piece, use a flat-head screwdriver to pop it out...you may need to disconnect the light connector, and the cigarette lighter connection.. Once the plastic piece is out, you will see a large white box, the filter is inside this box. There are two yellow clips that need to be slided to the left/right. The box then pops out from below and the folded-filter will fall right out
Good luck..i hope this helps..please rate me a fixya.

Remove the contents of your glove box, and open it fully by pressing inward on the middle at both outer sides. Drop the box door down. Look into the dash area. You will see the tray that holds the Cabin Air Filter.

the filter is behind the glove box. pull the 2 clips on both sides of glove box. then remove glove box. the filter cover should be right there and just unclip the cover and replace filter.
