nothing unusual happened, this is what 1985 Turbo's wiring eventually end up
looking like, this was the vegetable base insulation that Saab used at the time....nice is it not?
Here's the After, a temporary fix but not too bad, I drilled the hole
on the side of the fusebox so i would get more wiring, as I had to cut
off quite a bit...and those old connectors were totally shot...
This is EXACTLY what happened to my '85 900 Aero. Same spot too. The wiring was routed so that the outer insulation around the bundle would fill up with water and rot away. Still, lasted 20 years, so can't really complain.
Anyway, I'd be driving along and the doors would lock and unlock, the power window and mirror on that side would just go haywire of their own accord. The only way to lock the passenger door was to use "up" on the power window. When released, the door would lock.
I too had to spend some time under there with some new wire.
