Just bought an 03 Expedition changing all the filters parts store sold me a cabin air filter but I can not find a location where the damn thing goes. My question is does the 2003 Expedition have a cabin air filter, I've seen some say yes and some say no but it was a dealer installed option??? Please help...

 

If equipped there will be a panel under the glove box. Remove the 5 or so screws, drop the panel and pull the filter out.
