Default No Hatch Ajar light

After searching the forum I've got to ask for help.

'96 Cpe and the "Hatch Ajar" light does not show in the dash. All of the courtesy lights work and the "door ajar" indicator works for both doors. I pulled the hatch ajar switch and there was no power to the switch. All the fuses are good unless I missed one. Any ideas would really be appreciated.

Thanks everyone.

No time right now, but when I get a chance I will check the FSM and see if I could get a definite answer.

However it is possible the switch might be a ground return from the CCM and have minimal voltage on it. Also check the bulb in the DIP panel and see if it is burned out.

I checked the wires going to the switch and there was no power. One side of the harness going to the switch goes to a ground. Clean and tight. If it's the bulb in the DIP panel, I may just ignore it. Does it show there, or in the speedo area like the "door ajar" lights? I'd appreciate you checking the FSM for me. That would be great.
Thanks

If you look in the mirror and see the hatch open, it's ajar. Just being funny. Good luck.

Never thought of that. So, if all of a sudden the little dog is gone, it's probably the same indicator......Thank you

Not sure how much I can help on your 96, I have a 94. We might need to re-group, not sure. Don’t know if your car is different than mine in that area or not. I to have a door ajar on my Speedo but I do not have a hatch agar light anywhere (speedo or DIP).

However when the hatch is open, the security light on the Speedo flashes. I did check the FSM and the agar switch which is normally open, goes to ground, and the other terminal goes to a CCM input terminal. The security light is part of the thief system and is driven by different inputs to the CCM and the logic in the CCM firmware.

So it looks like my "hatch indicator" is the security light. Is it possible that you never had a "hatch ajar light? If you did definitly have one, it must me a 96 item.

Thank you pcolt. You are absolutely right. You nailed it for me.
That's exactly what is happening. Thanks for saving me from a lot of work and insanity. I really appreciate the help.

I think the interior lights should also come on when the hatch opens.

I eventually got mad enough that I just said screw it and ripped the whole interior out.

They had the wrong light in stock. I'm still waiting for the right one. When it gets here I will post the part number.
