A common problem almost since new on the early 9-3 Sport Sedans with halogen headlamps is that the wiring for the headlamp bulbs degrades and falls apart. Saab makes a kit to fix this. I installed one today, here's a pic:
The result is a professional repair near as good as the original factory wiring.
A nice and affordable fix for an unforeseen problem. The kit is about 15 bucks.
