I tested the 4wd dash light, indicator switch, vacuum lines and the 4wd vacuum actuator. All of the components check out as serviceable and the vacuum pump pulls 24 psi at the pump and at other points along the vacuum system. When the engine is shutdown, the vacuum pump starts to drop pressure after about a minute, at a rate of approximately 1 psi per minute.
Still no dash light when everything is hooked up and I engage 4wd. Looking for further guidance.
Black vacuum line pressure on CAD actuator when 4wd is shifted into 4H is high than rest of vacuum lines, at 28psi.
