The cabin filter on the 1994 Chevy 1500 Silverado purifies air brought into the cabin of the truck from the outside through the window cowl. The filter's purpose is to remove dirt, dust, pollutants from exhaust fumes, pollen and other allergens. You should replace the cabin filter in your Chevy 1500 every 15,000 miles, more often if you live in a particularly dusty area or spend a lot of time off-road.
Locate the black filter housing behind the glove box on the passenger side of the vehicle. The cover for the filter housing is located on the right side of the housing.
Snap the cover off the housing with your fingers and pull out the flat, square filter inside the housing.
Slide the new filter into the housing. Take note of the arrow on the filter. The arrow must face away from the housing cover.
Place the cover onto the filter housing and snap it into place with your fingers.
