" I disabled alarm, created new problem......"


          

Four days ago I disabled my anti-theft alarm by pulling the two white 13-pin connectors that are attached to a white module to the left of the blower motor, which is behind the glove box. This took care of the alarm/lights going-off-at-will problem, but created a new one. After the first day I noticed that I hadn't heard the compressor for the air suspension run, and didn't hear any clicks and clacks from the suspension. Two days in and my front end started to droop slightly, while the rear looked higher than ever ( still no evidence of the compressor working ). By the morning of day four, the front was almost totally slammed, while the rear was still high as ever. Needless to say, I reconnected the white connecters to the module, put the ignition to "On" and the front end lifted back up immediately. ( I assume there is a small tear in the front bags, as it took four days to slam, and the back wasn't venting whatsoever ). Anyway........now I'm getting a "beep" from the message center almost every time I go over a bump, and occasionally you'll see the "Check air ride" flash on for about 1/10 of a second, than dissappear. On the ride home ( over a bumpy road ), the beep was happening at least 10 times a minute. I also noticed that the auto-glide on the passengers side seat stopped working, and it still doesn't work after the reconnection ( the driver's side only used to work when the passenger's door was open ).
So my question(s) are: (1) did I pull the wrong connectors to disable the anti-theft alarm? I did exactly what was mentioned on a recent post in this forum. I also was careful not to pull any other connectors than the white 13-pin ones. If these were the wrong ones, what are the right ones, or what else can I do to disable this? (2) What's up with the suspension? Again, I assume the front bags have small leaks, but that was/is not a major problem, as they inflate when necessary, which isn't that often. Did I screw something up electronically by pulling the white connectors? (3) Could the whole anti-theft alarm/auto glide seat malfunction have something to do with the door sensors? I never get a false "door ajar" warning as has been mentioned on the forums, so I'm stumped.
Thanks for any help with this. Gotta go disconnect the horn now that the random alarm is back in action!

I think you have a few unrelated problems here.

I disconnected one of my anti theft modules with no other problems.

I wouldn't worry about the auto glide until the air suspension was repaired. It is a separate circuit.

The leaking front airsprings should be replaced before any damage to your air compressor or relay happens.

If the rear is too high, that could be a sticking vent valve.

Check Eddies website for excellent information and products for your air suspension. Here's the link:

I believe the alarm module is Yellow, at least it was in my '93. I did the same thing and had no problems whatsoever.

You MAY have inadvertantly loosened a connector or something. I would take is all apart, hook the wires back up and see if everything works ok. The problems shouldn't be related.

When you disconnected your module, did you pull two connectors, or just one? I'm talking about the white 13-pin connectors to the lower right of the fan housing behind the glove box door. If you pulled only one, was it the right or left one? Any help would be appreciated. Thanks.

Here I was refering to the possiblity of the auto glide/anti-theft malfunctions having something in common, possibly the door switch?

I do plan on replacing these eventually, just haven't the time or desire right now. It currently is a rather slow leak, but it is a leak and will need fixed.

Thanks for the advice, I appreciate it!

I disconnected both wires from my module.
Check out the photo I took. The green freehand rectangle shows the module sockets. Sorry about the poor quality, but I wanted to show the glove box opening and the AC vent.

I checked my autoglide today. It works fine with the door open or closed.
Edit: I will reconnect the module when I find the problem.

Sorry, I meant to say that I disconnected both connectors from the module.

Thanks for the pics and the fast response. Those are the exact connectors I unplugged. I was careful not to remove/disconnect anything else, but the result ( on my car ) was to disable the anti-theft, and to disable the air suspension. Hmmmmm........this is a mystery. Thoughts anyone?! On a side note, the message center still beeps ( and tries to flash the "Check air suspension" ) when I go over bumps, but not as often. Also, on an unrelated side note, the auto-glide works again. Seems to be a bit finicky.

If you unplugged the two connectors shown in the photos above you did the right ones. If the air suspension is giving you grief I think the car has another problem that is seperate from your alarm problem. I unplugged my alarm five years ago and the air suspension has worked flawlessly since. Never a message on the center unless it is that stupid low washer fluid warning. Car rides level and the pump kicks on about when you would expect it to. The car lowers itself going down the highway and when you slow down and come on to an exit ramp it will start raising the car back up to a normal height. My friend had a 94 that kept sitting the front on the ground and I think it had some bad height position sensors on the suspension. He actually ended up switching his over to manual struts and got rid of his air bags. I don't think I would ever do that if I can avoid it. Good luck with the car.

Auto Glide
Passenger's auto glide on my 93 works sometimes while driver's side
works correctly all the time.

Air Bags
Per the L/M service dept, the front air bags go after about 8 years.
They develop hair line cracks in the rubber and slowly, very slowly,
loose air. No such problem with the rears per L/M. When mine went
flat over night, I decided to have them replaced when the car was 9
years old and had 65K miles on it. I have 86K miles on it now and the
rear are still okay. I bought the car new in MAY 1993.

The "Door Ajar" message (or faulty door closed switch) will not cause
the alarm to go off!

You can lock you car without arming the alarm system and you should
do this until you get time to correct the cause of the alarm going
off. Please read the post below for details:

#27028, "RE: My alarm system gone crazy, the alarm turns on by himself"
In response to Reply # 1


The alarm system can be armed in two ways:
1. Depressing simultaneously the 7/8 and 9/0 buttons on the key pad.
2. Depressing the lock button on the remote one time.

The alarm system will not be armed when you press the lock button
on either inside door panel prior to exiting.

The alarm system can be set off (horn & lights) by door lock switches
inside the rear side of the doors. There are two internal
switches in each door. The second switch is for the door ajar signal.
Both of the switches become gummed up with grease over time and can
malfunction. The result of a malfunction could be the alarm going
off 30 seconds after it has been armed, or while driving the car
for the first minute and the "Door Ajar" message comes up on the
message center.

The alarm can also be set off 30 seconds after it has been armed if
the hood pin switch is defective or gummed up with grease.

The most likely cause of your problem is the door latch closed
sensors inside the edge of both doors. The following link will
provide the best method to cure your problem. You should also clean
the hood pin switch while you're at it.

Thanks. Unfortunately, my alarm goes off whenever it feels like it, even without arming it ( don't have a remote, and almost never use the 7/8 9/10 buttons ). When opening the door, when turning it off, when closing a door, after sitting for a minute, after sitting for an hour, in the middle of the night after not driving it for a day. Very frustrating. Also, the suspension and alarm problem are somehow connected, as the suspension stopped operating after pulling the connectors, and immediately started working again after plugging them back in. Must be some weird gremlins in the electrical system somewhere!
