Hello To Fellow Brethren Of Blazer Enthusiasts:

I have a 1999 Blazer LS set up for RV towing with a differential disconnect. Today I am working on the 4WD, and I have run into a headache with the vacuum lines. I was in the field and could not get the front end hubs to engage.

I have replaced the vacuum actuator and the actuator cable. I also replaced the 2-wire switch on that end.

I was trying to locate the vacuum switch and discovered those lines were completely dry-rotted and none of them were connected to anything. Just laying on top of the transfer case.

So where do all of these lines go? One obviously goes to the vacuum actuator, but what about the rest?

Thanks for all replies...


Obviously one line goes to the vacuum actuator, but what about the other 3?
