Hey guys, we're supposed to get about 2 feet of snow dumped on us this weekend so I'm in desperation mode to fix my 4x4.

I believe I may have narrowed it down to the vac. line that runs from the actuator under the battery tray, to the front axle. I've got the 3 button system BTW. The cable is cracked and corroded completely in half down by the front axle. This would prevent vacuum from reaching and engagine the front axle correct?

Noteworthy is that when I press the 4hi button it lights up and stays on (until I tried it this morning that is and it just blinks) and I can hear the motor engaging or making some sort of noise.....but the front wheels receive no power.

Should I just go ahead and replace the actuator and switch at the front axle while I'm at it? Does anyone have a p/n for the cable that is corroded?
