I’ve been keeping our 12/1997 Saab 900s going for years now. The alternator is a 98’ (some parts could be from either a 97 or 98, thanks GM! The latest issue started when the top won’t close without 2 people guiding it up/down, then all the windows won’t raise unless you pull on them. Noticed the Rear Fog Light indicator on the dash is dim and gets brighter when I “try” to raise a window. The Rear fog lights are dim without the switch on. I removed the lamps and the car won’t start. Also the engine cooling fan doesn’t kick on for either speed, but I can Hotwire both relays and it works. No engine fault codes or issues indicate on my cheap scan tool. Just the typical “check brake lights” Checked battery cables and the grounds under the hood, reseated the ICE module connector.... I’m fairly good with electronics, seems like there is a common open ground for all the symptoms, but no schematic. Help!
