How to Change an Evaporator Core

Release the air conditioning pressure. This must be released into a recycling unit at an air conditioning repair shop approved by the EPA.

Use a screwdriver to remove the screws from the air conditioning unit. Take out the air conditioning unit under the dashboard. The unit must be turned upside down. Find the retaining screws that keep the two parts of the unit together. Place the screws to the side.

Flip the unit over again then manually take out the upper part of the housing.

Raise and remove the evaporator from its position in the lower housing. Slide in the new evaporator core and place it into the space where you just removed the old one. Reverse the previous steps to install the brand new unit.
