I just bought my Saab a few days ago knowing it needs some work done to it; however, I'm at a standstill. My radio will not turn on at all, and neither will my blower fan; the SID control knob also bugs out occasionally jumping two to three settings ahead. I'm not sure if the issues are related, if not I'm thinking the blower is just a bad resistor unit in the glove-box. When I'm driving with the thermostat no hot or cold it blows air from the outside, and the A/C turns on when I hit the button, just no fan movement. I'm a first time Saab owner so any help would be greatly appreciated .
