Note. A leak in the vacuum control circuit may occur during acceleration (slow leak) or may exist at all times (large leak), and may exist only when specific functions are selected (indicating a leak in that portion of the circuit). The vacuum hoses used in the passenger compartment control circuit are constructed from PVC plastic material. The vacuum hoses used in the engine compartment are constructed of Hytrel®. Because of the materials used, never pinch off the vacuum hoses to locate a leak during diagnosis. A golf tee can be used as a plug when it is necessary to plug one end of the vacuum hose for leak test purposes.

SPECIAL TOOL (ELECTRONIC LEAK DETECTION) H10PM Refrigerant Leak Detector With Battery 216-00001 or equivalent
| CAUTION | Good ventilation is necessary in the area where electronic A/C leak testing is to be carried out. If the surrounding air is contaminated with refrigerant gas, the leak detector will indicate this gas all the time. Odors from other chemicals such as antifreeze, diesel fuel, disc brake cleaner, or other cleaning solvents can cause the same problem. Using a fan to ventilate the area to be tested before proceeding with the leak detection procedure is helpful in removing small traces of contamination from the air, but the fan should be turned off during the actual testing. |

- Leak test the refrigerant system using the refrigerant leak detector. Follow the instructions included with the leak detector for handling and operation techniques.
- If a leak is found, recover the refrigerant. For additional information, refer to «AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING»(ref-232279-S03696491132006051600000) . Repair the system. Test the system for normal operation.

- Measure the length of the damaged area of the mini-tube vacuum hose.
- Cut a piece of standard 1/8-inch inner diameter vacuum hose approximately 25 mm (1 inch) longer than the damaged area of the mini-tube vacuum hose.
- Cut off the mini-tube vacuum hose on each side of the damaged area.
- Dip the mini-tube hose ends in commercially available paint thinner containing methyl ethyl ketone (MEK). This solvent will seal the mini-tube in the vacuum hose.
- Insert the ends of the mini-tube vacuum hose approximately 9 mm (3/8 inch) into the ends of the standard 1/8-inch repair vacuum hose section.
- Shake the repair joint after assembly to make sure the solvent is dispersed and the vacuum line is not plugged.
- Test the system for a vacuum leak in the repair area. Use a vacuum pump.
