Hey guys, so my 4wd isn't working, found that out in a mud hole... I don't think its the tcase cause it shifts fine. Is there any way to check to see if the actuator is working? my vacuum lines are good i checked those Sunday.
check your vacuum lines at the front axle..when you have the transfer case in 4x4 the yellow line should have vacuum..when you have taken it out of 4x4 the green line should have vacuum..if it is not doing this then replace the vacuum switch on the transfer case...if the vacuum is as listed above then the actuator on the front axle itself is probably the problem
its the vacuum switch at the tcase. Im not getting any suction.
ok..before you replace the switch,make sure you have vacuum coming to the transfer case switch from the engine via the red line..if not then trace it back and see if it is busted or not connected to get engine vacuum..if you do have vacuum on the red line at the t-case switch then replace the switch..they are only about 10 bucks
