How are the plastic cowl pieces removed from a 94 Ford Escort LX?

remove the cowl <the plastic piece below the wipers> and on each corner by the finders on drivers and passengers sides there is a little drain hole that will fill with dirt and gunk, use a piece of stiff wire and clear out the drain hole so water will drain and it should stop leaking into the car

Hello. Welcome to FixYa. Please allow me to help out here.

Yes, there is a hole under the wiper motor. This is where the heater/defroster gets fresh air from.

If you are getting water in the heater box, the drains that keep the water from backing up, and entering the hole, are blocked. You will need to have the cowl panle removed, and any debris under the cowl removed and cleaned out.

The drain is a runoff from the outside wiper grill, the open area under neath the wiper grill is for outside air to suct in from your a/c blower. The only way to repair it is to the body shop this will take alot of $$$$$$$$. but for me I'll take a rubber glue tube, cut a piece of rubber inter tube and apply the glue patch it from the inside............where the water is coming in. This work for about 5 years now since I live in the pacific rim, rust is very but here.......good luck

Do you have a sun roof? I imagine you do.

Under the roof cover there is a tube on each side of the car that drains the sunroof area to the ground. Either a tube has been disconnected or come loose. This will cause severe mold and mildew problems if not fixed soon.

your blower resistor is bad

pull the plastic grate cover off the cowl at heater AC outside air intake at the base of the windshield and check to see that the cowl drains are not plugged with leafs or other debris, this is the common cause, if the drains are clear seal around the cowl air intake with automotive silicone caulking.
