The interior lights on my 91 Vert flicker. Especially when I accelerate. I noticed the warning 'door ajar' comes on, even though the doors aren't ajar.

In the middle of the night, the alarm goes on and off at random. I'm guessing the alarm thinks the door is open since the lights flicker, as if someone was tampering with the door.

Any clues?

Thanks

My interior light flickers when I hit a bump in the road. I'm thinkin' that maybe the door need adjusting. Hope somebody knows.......... :crazy:

Check the door switches, this happened to me also. In my case the switch for the hatch was faulty.

Check the door switches. They may need ajusting or replacement.

Its a bad door switch. They look like plunger buttons, black. One for each door and one on the hatch. Could just be loose or just need adjusting and not replacing.

Hinge pins and bushing time :seeya

Until you get the problem fixed, recommend you lock the doors with the keys, this does not arm the system. Electric door lock button arms the system.

Maybe for a test, dark area, start to wiggle/giggle, bump door. See if interior lights come on. Same thing back by hatch. Open doors, grab outside edge of door and lift vertically, checking for play. Also, check the little plastic stops for the door open/closed switch.

My money says left door ajar switch or pins/bushing.

Sweet dreams.

Door or hatch switches need checking. Since you're getting the door ajar light when the doors are closed, I would bet it's one of the door switches. :yesnod:

If you look at the switches in the doors, you see a small pin in the plastic plunger. The small pin is what actually contacts the body and turns off the lights. If the pin is too far in the plunger, the plunger won't be pushed in far enough. With a small flat blade screwdriver, pry both of the pins out slightly.

I would service the driver's "door ajar" switch first.

Mine flickers occasionally but not bad enough yet to set off the alarm when parked and locked.

Pull that small pin out a little on the doors. I had the same problem, I learned after I adjusted the door pins not to slam my doors. It was free info. I received here on the forum :yesnod: it worked

Not in my case, I disabled the PKE and it the alarm still went off, the only way I solved it temporarily was to pull the fuse.
