Insufficient Cooling "Quick Check" Procedure
WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
Perform the following "hand-feel" procedure to get a quick idea of whether the A/C system has the proper charge of Refrigerant-134a. The air temperature must be above 21 °C (70 °F) for most models.
- Warm up engine. Run the engine at idle.
- Open the hood and all the doors.
- Turn the A/C switch ON.
- Set the temperature control to the full cold position.
- Set the blower speed switch on the maximum speed setting.
- "Hand-feel" the temperature of the evaporator outlet pipe. The pipe should be cold.
- Check for other problems. Refer to Pressure-Temperature Relationship of R-134a .
- Leak check the system. Refer to Electronic Leak Detectors . If you find a leak, discharge the system and repair the leak as required. After completing the repair, evacuate the system and charge it.
- If there is no leak, refer to Pressure Test Chart (R-134a System) .
