Finding Leaks In the Evaporator Area

1. Start the engine, and turn on the A/C.

2. Set the Fresh/Recirc button to Fresh, then turn the blower motor to High for 15 seconds.

3. Turn off the blower, and set the Fresh/Recirc button to the Recirculation position. Wait 10 minutes to allow any leaking refrigerant to accumulate in the vents.






4. Attach the flexible probe extension, and insert it in the center grille.

5. Turn the blower motor to Low for about half a second; this will force any accumulated refrigerant out through the vent.
