The air filter cover seems to be stuck. I have removed the two front bolts and no other clips or bolts are on the air cleaner cover. It won't budge.

TRY TWISTING IT ONE WAY OR THE OTHER! IT MAY HAVE A MOUNT BOLT INSIDE THE TOP COVER!

The "AC Filter" refers to the Air Cleaner Filter. That is in the engine compartment in the air cleaner assembly. The cover is held on by a couple of clips. Undo the clips and remove the cover. Then you can remove the Air Filter and replace it with a fresh one. (Can be purchased at Walmart even.)

(The coolant lines inside the air cleaner housing may be warm. Do not open the hot air valve when cleaning the inside of the air cleaner housing)

The air filters are located within the engine cover. You need to pop the cover off and access the bottom of the cover. There are 8 20 torx bolts. The cabin filter is located in the rear engine compartment on the pass side over the battery. It is held in by 3 clips.

You do not have to remove the wheel unless you have th 6 cylinder engine (2.3l). Then yes you do:

Disconnect Negative Battery Cable
Remove the air cleaner and hose from between the air breather/cleaner and throttle housing
Relax the belt tensioner off the belt and pry off the belt
Remove the right front wheel, black belt cover/protector, and the wheel hub nut and slide the hub off the drive shaft/outer Cv joint
Disconnect the alternator, remove the alternator/air intake hose, 2 bolts that hold the alternator in and remove it through right-hand wheel housing.

Yes, this is immensely annoying. I hope you figured it out...
