MK3 alarm fix

I finally fixed my factory alarm after chasing the problem off and on for months. The alarm would not set or lock the doors with the key fob. The doors would lock manually with the key, but would go into standby mode (slow blink) and the alarm would go off randomly. I started out by checking all the door/hood/trunk switches, broken wires and bad connections. Couldn't find anything bad/wrong/unplugged etc...

One day I noticed the interior "door open" light would not work with any door open. I pulled the mechanism down and took it apart. I removed the pc board and scuffed up the area where the pc board seats and the alarm now works. Apparently there was a bad connection and now it works fine.

Just thought I'd share this if anyone is chasing down a MK3 alarm issue and cannot find an obvious problem. :)
