To check the glow plugs, disconnect the power cable to the top of each one and check the resistance between the central terminal and the outer casing or cylinder head (ground) it should be below 1 ohm. Normally they will start on 3, but if you have 2 down they won't start from cold.

The buzzer could be anything from the light switch, ignition tumbler, the wiring, to a bad buzzer itself.

Suggested Repair

Disconnect the power cable at the top of each glow plug and measure resistance between the central terminal and the outer casing or cylinder head. It should be below 1 ohm. The engine may start with three working plugs, but two failed plugs can prevent a cold start. For the lights-on buzzer, check the light switch, ignition tumbler, wiring, and the buzzer itself.

Conversation Summary

The owner of a Jeep Cherokee 2.5 diesel asked how to remove and test the glow plugs, whether a loud starting noise was the starter bendix and how to fix it, and why the lights-on door buzzer and seat belt warning did not work. The expert explained a resistance test for the glow plugs and said the buzzer fault could be the light switch, ignition tumbler, wiring, or the buzzer. The starter noise and seat belt warning were not addressed.
