4wd vacuum actuator - vacuum troubleshoot
I tested the vacuum at the transfer case switch - 20lbs at the red line.
When shifter is in 2 wheel drive, I get no vacuum to the yellow or black lines running to the actuator. I do have vacuum in the green line which i believe is the indicator light.
In 4wd i get vacuum to both the yellow and black line and also to the green line.
I thought i should have vacuum to one side in 2wd and vacuum to the other in 4wd. Why am i getting it on both sides in only 4wd?
