I would like to know the location of the cabin air filter on my 1998 Lincoln Town Car (Cartier) if there is one. The airflow for my heater seems to have dropped off to the point there is almost no airflow through the vents. Any help is appreciated in advance.

Passenger compartment fuse panel fuse number 7 15A and fuse N. 12 15 A.

The car will lack power but seem to run smooth just slow to accelerate.

Have you ever replaced the cabin air filter (AKA pollen filter) I would suggest you do that and see if it cures the low air flow problem. If the problem persists then you may have an obstruction at the cabin air intake area like a plastic bag.

For instructions go to www.micronAir.com you can print ut the instructions.
If you go to micronair.com and try to find the instructions for changing a lincoln ls cabin filter you will be disappointed because the lincoln is not one of the cars found on this list. A general search of lincoln ls & cabin filter will yeild many results with the pertinent information.

The cabin air filter is located under the cowl. Open the hood, proceed to the passenger side of the car and you will see where the right side wiper is resting, under the black plastic cowl there the cabin filter is.

I don't think the towncar even has a cabin air filter in 1995

If you notice a 'sweet' smell, or windows tend to fog up, it's your cars heater core leaking. The heater core is located under the dash, passenger side, it's like a mini radiator. The cars cooling system directs hot coolant to it so you can have heat. To change it is an involved procedure.
If there is no evidence of the anti-freeze smell or windows fogging up, and u have been using your air conditioner, it would be a blockage in the drain tube from the a/c. The end of the tube is located under the car on the passenger side , behind the front wheel. The blockage needs to be removed, and will solve the problem. Let me know what u find Curt
