Subject: Re: 9000 alarm

I had a '93 9000 with an bewildering alarm problem. It would activate for no reason at all. It never happened at my home because we don't lock our cars (raccoons don't steal cars). Two dealers and one SAAB specialist gave-up on fixing it because they couldn't reproduce the problem. I finally started locking the car at night just to see what would happen. On the 4th night it triggered. As I stumbled out the door with the key, I thought " Damn, I left the interior light on." I opened the door, the alarm stopped and when I shut the door the light went off. "What the f---?" The same thing happened a few nights later. So I said to myself, "Self, there's a connection here. Since you have no schematic, punt. The alarm system is basically a bunch of sensors that trigger a relay. The doors obviously have sensors. These sensors probably also trigger the interior light. But the interior light is also run buy a snazzy delay relay. What if the delay relay become apoplectic and turns on the light for no reason? Maybe it could also trigger the alarm. So I removed the glove box and replaced the interior light relay. End of alarming problem. Tom L.
