To save anyone else the pain, here's what I (eventually) found: "All that is required is follow the wire from the instrument cluster down into the dash to the box, which has a reset button on it. It might be easier to reach from underneath." Yes, it's an 8V CIS. I'll find the button, and then I'll be able to take the piece of duct tape off of the instrument cluster. Fun buying an almost 20 year old car from at least two non-saabish owners. At least 3 of the rotors were warped, the gas cap was, well, not just wrong but didn't seal _at all_, the dashboard had been pulled out to install a POS radio, the heat didn't work, and the car had a HUGE vacuum leak. The lack of heat and the vacuum leak were, of course, the rod to the heater control valve from the dash panel, and the vacuum switch connector to the back of the switch. Put those back in, fixed the no-heat, fixed most of the running problems, fixed the heater control stuff, fixed the moan from the vacuum reservoir check valve (due to constant flow). Replaced about 8 feet of vacuum hose that was slightly crunchy and/or swollen. Brake rotors (front) went well, but I had to make the rotator tool for the pistons because I lent mine out (anybody? Hello?) and don't remember to whom. Bled the brakes, they still sucked. New brake master cylinder, all better. Rebuilt cylinder was only 30 bucks more than the rebuild kit, so I went the lazy way and used it. Brakes now work great. > 2) normal.

ISTR that there's an offset cog type thing so I can't screw up the timing. Need new plugs and to time the beast anyway, might as well do cap & rotor while I'm at it, I suppose. Valve cover leaks too, oddly enough, and it looks like when I have the distributor off is the perfect time to deal with that. Thanks, Dave Hinz
