Does anyone know where the cabin filter is???

I have been looking for the cabin filter for the past 2 days for my 1997 chevy lumina. I removed the cowl on the passenger side and I still cant find the cabin filter. If anyone knows where it is ,please let me know.

Thanks
Dan

once I fould one in the glove conpartment that was on a
97 pontiac minivan but and a car I have no clue. If you are haveing problems with not enough air coming through the vent you can take out the heater core and wash it out it helps for sure but it is a pain in the ass good luck.
