How so I test the servo on the cruise control? 850 1994

Use a vacuum pump. If the servo's good, you'll see it depress the gas pedal and hold vacuum.
Brake pedal switches (and/or clutch pedal on MT cars) being NG or out of adjustment is the most common problem on 850s. I've also seen bad vacuum lines near the battery.
