Coil Resistance Test
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.
- Disconnect the wire harness connector from the A/C clutch coil connector.
- Use an ohm meter and Back Probe Tool (special tool #6801, Terminal Probe) and measure the resistance of the A/C clutch coil at the coil connector terminals.
- See A/C Clutch Coil Specifications table for acceptable A/C clutch coil resistance. Specifications apply for a work area temperature of 21° C (70° F).
- If the A/C clutch coil reading is below specifications, the coil is shorted and must be replaced.
- If the A/C clutch coil reading is above specifications, the coil is open and must be replaced.
