4WD issues

[94PaT4R]

I am new to imports in general. I just bought my first T4R the end of last week. We had snow this week and low and behold the 4WD does not work. What is the first thing i should look at? Its really irritating. If yall could help me out I would greatly appreciate it. Thanks

Oh yea its a 94 3.0 V6.

This is usually the problem.

Automatic Disconnect Differential(ADD) actuator located on the front differential, it is supposed to engage the front differential to provide 4 wheel drive, this actuator is vacuum operated from a vacuum switching valve, the most common problem is that a vacuum hose may have become disconnected, another problem may be that the actuator vacuum pipes may have gotten clogged up with rust or other foreing matter, the 4x4 indicator switch that turns the light on the dash on is directly connected to the front differential so if the actuator does not engage the light will not turn on and there is no 4 wheel drive

haha you know what i was reading older threads and saw about the vacuum lines i took it off and bypassed the spindle looking thing and it popped right into 4WD blew the lines out and they were clogged, hooked it back up and works like a champ thank you for your input though.
