Procedure to Remove the Old Cabin Filter First off, you need to open the glove compartment; you'll see two screws on top of the glove compartment and two at the bottom of it.

Remove each one of them one by one with the help of a Phillips screwdriver, and then unhook the stop bar which you can find on the right side of the glove compartment .

Next, pull the glove compartment out - while pulling the glove compartment out we disconnect the light wire .

Now, you should be able to see two tabs on both sides of the cabin filter which we press towards the middle of the compartment and then we remove the cabin filter cover . After this, slide the filter out of the housing .

Putting the New Filter In Place Now, you can easily insert the new filter in the filter housing making sure the "up" arrow printed on the filter points towards the roof of the Endeavor and then we replace the cabin filter cover.

Next, insert the glove compartment back into the dash and while it is half way through you need to reconnect the light wire.

Finally, reconnect the stop bar over the hook and finally replace the four screws to hold the glove compartment firmly in place. And, that's it - you've just learned how to change cabin filter in Mitsubishi Endeavor.

Not sure about that car in specific but most cars have their cabin air filters where the front passengers feet would be. There maybe a plastic cover you need to remove and maybe a screw and the filter should drop down.
