A dash warning saying the AC Filter needs chaging poped up for a few seconds on my 02LS UL w/ 57k. Is this the cabin filter in the glovebox or the rear AC filter accessed through the trunk? If I replace the filter, how do I reset the warning system? Thanks in advance.

 

My light is also coming on. Anyone know the answer?

 

With the ignition "On", press the "off" button in the front AC control for 4 seconds until it beeps then you will see the display say "AC filter reset".

The instructions are in the owner's manual if I recall correctly.
