Q: 2000 Jeep Gran Cherokee 4.0. If low and high AC pressure switches are grounding out, and clutch won't engage, does that mean compr

Hello Jim, thank you for writing in. To determine what the issue is, you need to start by checking the clutch coil for full battery power (12 volts ideally). If it is, then you know clutch should engage when prompted, and you may need to replace the entire assembly. If by "grounded out" you mean that the battery voltage is shorted out and not reaching the clutch coil, then you need to find the short. If you do not have full voltage, you will need to focus on the wiring from the fuse box to the clutch coil. A clog in the system which robs the compressor of refrigerant will also cause the compressor and clutch assembly to fail. If this is the case, again you have to replace the entire assembly.
