4 wheel drive vacuum lines

Below is a diagram for your transfer case. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

I have a chevy blazer s10 4x4 1997, i need the vacuum hose diagram, i lost some hoses in the last repair of the automatic transmission and want to use the 4x4, thanks in advance

hope this helps

The hose conected to the transfer back, and other go back the truck, and one connected to a box in the front, where should be connected?

one hose is connected to engine vacuum, one hose goes to the front diff actuator on pass front fender area under battery and the other hose is just a vent

the vacuum switches on the transfer case fail all the time so if your still having a problem then repalce that too

I will try with the information you provided me. Thanks

When 4x4 is engaged, there is transmission fluid being drawn into the engine via vacuum. Is this a vacuum actuator problem or another booger.

Could be the vacuum switch on the transfer case.Have any of the vacuum lines been moved or any work done on it? If the vent line is put on the engine it can do that.If nothing has been changed recently, it is most likely the vacuum switch on the transfer case.
