I tried the tapping the column and lubing with dry graphite. No change.

I also looked inside the dash, but have not located the magic box. Nothing was attached up near the speaker. I'll try to attach a pic.

looking in through the glove box:

from the speaker grille looking down:


sorry about the pic size...

That'* strange, I am not quite sure where your'* is located then. But here are some pics of mine.

This is a downward pic from the speaker cutout.


Upward from glovebox.


Overview of area above glovebox [notice how i have no glovebox, so mine may be slightly more 'accessable' if you will].


The red circles represent the alarm box [obviously]. It even has a pretty purple wire hanging out for the original key fob. 90/91 were supposidly the only years to have a key fob equiped alarm, but 89 had them too. Mine was dealer installed though.

My manual is at Bill'* house. He'* going to try to take a look at it for us later.

I'm not surprised that Marty is not finding the alarm module according to the pics. Justin and I compared wiring diagrams in the past and there were many differences between the 89 and 90. This is what makes me think that it'* not going to look like Justin'* alarm module in a 91. It will probably be in the same general location but usually can not be seen through the glove box. I'm thinking next to the keyless entry module which is directly above the glove box opening or next the the DIC module which is equally as high in the dash but farther forward.

I'm pretty certain that Justin is correct when he says that the door switches for the DIC are also used for the alarm. The plungers that you see in the door jambs are only for the interior lights. It seems to me that someone had a problem with the alarm in a 92-99 and it ended up being the trunk switch. The DIC didn't show that the trunk was open though. It was easy to test simply by temporarily disconnecting the connector near the trunk latch and see if the Security light returns to normal.

Still looking. I did find out that the Hella relay should be for the headlight washers. I also dropped the sound shield under the drivers' dash, but cannot see anything of interest yet. And the only thing directly behind the radio is an a/c duct.

I tried to get out the one silver box above the ecm tonight. It was held in by one 10mm nut, which was removed easily. Getting the box out was another matter. There is absolutely no room to swing it around. The box sits above the ecm, behind the glove box, and to the left of the speaker opening. The wire looms are too tight on the right side to allow any space to be created. I nearly got my arm stuck trying to find a way to wiggle it out. It might have more room if I unplugged the two connectors, but it is difficult to see the correct way to release without breaking any plastic.

Does anyone know what a 'newer' (post-92) anti-theft module looks like?

the alarm module for teh 90/91 is under the foot panel on the DRIVER'* side. if you drop downt the panel, its way up almost behind the instrument cluster. theres about 30ish wires coming out of it. Justin your alarm module doesnt look factory at all by the way the wires are connected. the 90/91 module is like a harness rather than individual wires plugged in.

hm that'* weird. Oh well, i know it was dealer installed, but that'* all i know about it. it also had a key fob, which is long gone unfortunately.

Justin, I had a similar (dealer installed) alarm on my '90 Trooper. I also have a similar variant, Clifford alarm on another car. They were popular in the mid- to late-eighties.

As for the anti-theft module being behind the cluster... I am not sure which bundle it would be back there. There are several on either side of the steering column. I cannot reach anything from below (besides the cruise control module). Do I need to pull the cluster to see back there?
:?:

if i remember right, its up where the brake pedal switch is. its a black box. you have you remove the footwheel and the ABS module to get up in there.

hmm... i wonder if I have that? I remember when I pulled the dash there was something like that. If you do divulge into it, you mind taking some pics? mucho appreciated

im sure you do, my wire diagram says 88-91 bonneville'* are there. that module you have on the passenger side may just be the keyless system your mother had added. its prolly tied into the security system on teh drivers side
