To find it, you'll need to:
1. Consult a Repair Manual: A repair manual specific to your 2002 Dodge Intrepid (Haynes or Chilton are good options) will show a diagram with the exact location of the low-pressure switch. This is the most reliable method.
2. Visual Inspection: Carefully examine the AC lines and components in your engine bay. Look for a small, usually electrical, switch connected to one of the low-pressure AC lines (thinner line). It might have wires connected to it. The lines themselves are usually metallic and are fairly easily identifiable near the compressor.
3. Follow the AC Lines: Trace the smaller (low-pressure) AC line from the evaporator (located inside the car, behind the dash) towards the compressor. The switch is likely somewhere along that line.
Safety Precautions: Before attempting to locate this switch, ensure your vehicle is turned off and the engine has cooled down. Also, be aware that AC system components are under pressure even when the system is off. Avoid contact with any refrigerant lines or fittings.
If you are uncomfortable performing this task yourself, it's best to have a qualified mechanic locate and inspect the switch.
