saab_900turbo

hey all, i have a 1986 9000 turbo and i am having troubles with it runnning at high voltage. When it idles it is at about 12.5 volts but when driving i am at around 19 to 19.5 volts. Not sure if its mt alternator going bad or voltage regulator or something. Hope one of you will have some answers for me. Thanks!

voltage regulator I think...go to advance auto parts, they do electrical system checks...

well i got the voltage regulator replaces and running well now. But, when i was running at 19 volts my heater blower quit working. Does anyone know if there is a blower motor relay somewhere.

I would say that you fried the resistor that controlls fan speed. Not sure where it is on your car though...
