lesabre cabin air filter

Does anyone know if a 1993 Lesabre has a cabin air filter, and if so, where is it and where can I get one?
Thanks

No, it does not have one.

Thanks. So if I think that there's not enough air velocity inside, I should check to see if the cowl is clear? It has a new blower as of a few months ago due to squeaking, so I doubt it is a blower issue (was like this before the replacement too).

Lack of air flow could be due to several things, most common are dirty or partially clogged evaporator, or improperly aligned blender doors. Do you feel air coming out the defrost and floor vents, along with the dash vents?

Make sure the blower motor rotates in the proper direction and the fins, if metal ,on the fan are not rusted away.
