Replace the green plastic tab back onto the bolt. Spray all moving parts of the lock and latch assembly with the aerosol lubricant. Wipe clean with a shop towel. Replace the liftgate trim, and tighten bolts with screwdriver.

Open and fully extend the liftgate with a friend supporting it in the air. Using a screwdriver, remove the old support bolts from the liftgate and vehicle until the support arm comes free.

Some multimeter models additionally read temperatures, inductance, frequencies, capacitance and duty cycles.

Hold the red probe on the multimeter to the positive port on your battery. Hold the black probe on the multimeter against the frame of your Cherokee. A working battery will provide a voltage reading of 12.6 volts on the multimeter. If you read any voltage amount less than 12.6 volts, replace your battery.
